musl-cross-make/litecross/Makefile
Rich Felker ddc9f102de fix build for s390x due to wrong long double ABI default 
musl uses IEEE quad for long double on s390x. current versions check
for mismatch and hard fail at configure time if the compiler is wrong.
with older versions, mcm silently produced a broken toolchain/libc.
