In preparation for removing some of the MIPS compiler intrinsics from arch/mips/lib, first update the build of vmlinuz to use the generic ashldi3 from lib. Both ashldi3 and bswapsi objects need to be built with different CFLAGS for inclusion to vmlinuz rather than simply including the object built for the main kernel image. The objects cannot be built directly from source, since CONFIG_MODVERSIONS changes cmd_cc_o_c to prevent this. Split the rule to ship ashldi3 and bswapsi from the relevant source locations. These files make no reference to other files in their directory, so the additional CFLAGS are apparently unnecessary - remove them as well.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
