Before this commit, glibc headers did the following mapping: * (zig) mipsel-linux-gnu => (glibc) mipsel-linux-gnu * (zig) mipsel-linux-gnu-soft => (glibc) (none) * (zig) mips-linux-gnu => (glibc) mips-linux-gnu * (zig) mips-linux-gnu-soft => (glibc) (none) While the glibc ABI stubs used the (zig) gnueabi and gnueabihf ABIs, and the stage2 available_libcs array listed: * (zig) mipsel-linux-gnu * (zig) mips-linux-gnu The problem is the mismatch between the ABI component of the headers and the stubs. This commit makes the following clarifications: * (zig) mips-linux-gnueabi means soft-float * (zig) mipsel-linux-gnueabi means soft-float * (zig) mips-linux-gnueabihf means hard-float * (zig) mipsel-linux-gnueabihf means hard-float Consequently, the glibc headers now do this mapping: * (zig) mips-linux-gnueabihf => (glibc) mips-linux-gnu * (zig) mipsel-linux-gnueabihf => (glibc) mipsel-linux-gnu * (zig) mips-linux-gnueabi => (glibc) mips-linux-gnu-soft * (zig) mipsel-linux-gnueabi => (glibc) mipsel-linux-gnu-soft The glibc ABI stubs are unchanged, and the stage2 available_libcs array's 2 entries are modified and it gains 2 more: * (zig) mipsel-linux-gnueabi * (zig) mipsel-linux-gnueabihf * (zig) mips-linux-gnueabi * (zig) mips-linux-gnueabihf Now everything is consistent. Zig no longer recognizes a `mips-linux-gnu` triple; one must use `mips-linux-gnueabi` (soft float) or `mips-linux-gnueabihf` (hard float).
