On mips*/mipsel* neither "abi" nor "llvm-abiname" is written, so rustc's stricter check fails. Cover every MIPS tune shipped in meta/conf/machine/include/mips/ arch-mips.inc's AVAILTUNES: arch=mips / mipsel                      -> o32 arch=mips64 / mips64el, ABIEXTENSION="" -> n64 arch=mips64 / mips64el, ABIEXTENSION=n32 -> n32 Note that the mips64-o32 / mips64el-o32 tunes (o32 ABI on a 64-bit MIPS CPU) get MIPSPKGSFX_BYTE="" from arch-mips.inc and therefore TUNE_ARCH="mips[el]"; they fall into the 32-bit branch above.
