musl-cross-make/patches/gcc-4.9.3/gcc-ssp.diff
rofl0r df82dd95d8 add patches for gcc 4.9.3
at least mips support is broken, but microblazed and possibly other
archs work.

while building mips the following error was encountered:
Mode = sf\|df
Suffix = si\|2\|3

xgcc: error: subsf3: No such file or directory
make[3]: *** [subsf3.o] Error 1

this seems like a bug in a shell command that's invoked during the build,
possibly a sed command using GNU-only syntax.
