Refactor the build system for easily adding crates Before this patch, if you wanted to add a crate to the build system you had to change about 100 lines across 8 separate makefiles. This is highly error prone and opaque to all but a few. This refactoring is targeted at consolidating this effort so adding a new crate adds one line in one file in a way that everyone can understand it.

# NATIVE_LIBS
# This is a list of all native libraries which are built as part of the
# build process. It will build all libraries into RT_OUTPUT_DIR with the
# appropriate name of static library as dictated by the target platform
#
# NATIVE_DEPS_<lib>
# This is a list of files relative to the src/rt directory which are
# needed to build the native library. Each file will be compiled to an
# object file, and then all the object files will be assembled into an
# archive (static library). The list contains files of any extension
#
# If adding a new library, you should update the NATIVE_LIBS list, and then list
# the required files below it. The list of required files is a list of files
# that's per-target so you're allowed to conditionally add files based on the
# target.

rustdoc: Migrate from sundown to hoedown This primary fix brought on by this upgrade is the proper matching of the ``` and ~~~ doc blocks. This also moves hoedown to a git submodule rather than a bundled repository. Additionally, hoedown is stricter about code blocks, so this ended up fixing a lot of invalid code blocks (ending with " ```" instead of "```", or ending with "~~~~" instead of "~~~"). Closes #12776

Move extra::flate to libflate This is hopefully the beginning of the long-awaited dissolution of libextra. Using the newly created build infrastructure for building libraries, I decided to move the first module out of libextra. While not being a particularly meaty module in and of itself, the flate module is required by rustc and additionally has a native C dependency. I was able to very easily split out the C dependency from rustrt, update librustc, and magically everything gets installed to the right locations and built automatically. This is meant to be a proof-of-concept commit to how easy it is to remove modules from libextra now. I didn't put any effort into modernizing the interface of libflate or updating it other than to remove the one glob import it had.

Implement flexible target specification Removes all target-specific knowledge from rustc. Some targets have changed during this, but none of these should be very visible outside of cross-compilation. The changes make our targets more consistent. iX86-unknown-linux-gnu is now only available as i686-unknown-linux-gnu. We used to accept any value of X greater than 1. i686 was released in 1995, and should encompass the bare minimum of what Rust supports on x86 CPUs. The only two windows targets are now i686-pc-windows-gnu and x86_64-pc-windows-gnu. The iOS target has been renamed from arm-apple-ios to arm-apple-darwin.

add back jemalloc to the tree This adds a `std::rt::heap` module with a nice allocator API. It's a step towards fixing #13094 and is a starting point for working on a generic allocator trait. The revision used for the jemalloc submodule is the stable 3.6.0 release. Closes #11807

mk: Build jemalloc with -ffunction-sections It's quite possible that small programs don't use all of jemalloc, and building with -ffunction-sections and -fdata-sections allows the linker (via --gc-sections) to strip out all unused code at link time. This decreases the size of a "hello world" executable for me from 716K to 482K with no measurable impact on link time. After this patch jemalloc is still the largest portion of our hello world executables, but this helps cut down on the size at least somewhat!

mk: Add support for musl-based builds This commit adds support to the makefiles, configuration script, and build system to understand MUSL. This is broken up into a few parts: * Any target of the form `*-musl` requires the `--musl-root` option to `./configure` which will indicate the root of the MUSL installation. It is also expected that there is a libunwind build inside of that installation built against that MUSL. * Objects from MUSL are copied into the build tree for Rust to be statically linked into the appropriate Rust library. * Objects for binary startup and shutdown are included in each Rust installation by default for MUSL. This requires MUSL to only be installed on the machine compiling rust. Only a linker will be necessary for compiling against MUSL on a target machine. Eventually a MUSL and/or libunwind build may be integrated by default into the build but for now they are just always assumed to exist externally.

Make sure rsbegin.o and rsend.o get packaged with target lib artifacts. Also, unified libc startup objects finding logic with that of the `-musl` target, since conceptually they were doing the same thing.
