9a85ed03da runtime: add the --without-libatomic configure option 
This adds the --without-libatomic configure option, which is useful for building libgo
with a non-gcc compiler.

It disables libgo's dependency on libatomic. This
is useful for platforms where it is known that the libatomic runtime
functions are not required, or where the compiler automatically
provides an implementation of them.

6c76a95d1b runtime: ask $GOC rather than $CC for the version and multi-os-directory 
The Go compiler may have different values for these than the C compiler.

33a9145bb7 libgo: Build math package with -ffp-contract=off on non-x86. 
http://golang.org/issue/7074 shows that not using
-ffp-contract=off produces the wrong result for math.Log2(1)

71d0d50aa3 go/build: Set GOARCH on arm64 systems. 
I am reliably informed that the architecture name and letter for the
plan9/inferno compilers for 64-bit ARM systems will be "arm64" and "7"
respectively, so let's get that bit in nice and early.

fdbc38a6e8 compiler, runtime: Use function descriptors. 
This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct.  The first field of
the struct points to the function code.  The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions.  For each call to a function, the address of the
function descriptor is passed as the last argument.

This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.
