gcc: Add support for building musl configuration
Most of these patches are already in gcc 6.0/master but we still need them for older gcc, they have been tested in meta-musl for quite some time (From OE-Core rev: 30a0cc2ef72399b84da4903e697f258f79852fc9) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
