//build/toolchain/musl-host-gcc: implement
This is a cc_toolchain which runs on x86 systems with Linux/gcc and
targets Smalltown via static musl builds.
It is currently unused, but can be tested by trying to build any
cc_binary with
--crosstool_top=//build/toolchain/musl-host-gcc:musl_host_cc_suite .
Test Plan: This has been tested manually by running it against a simple cc_binary. Another revision on top of this will attempt to build mkfs.xfs with it.
