lib/systems/platforms.nix: fix broken mips32 detection
Prior to this commit, nixpkgs would assume that every little-endian mips32 system was a "fuloong2f_n32". Not only are there plenty of mips32 chips other than the fuloong, but the fuloong is actually a mips64 chip! Note that the "n32" ABI is (confusingly) an ABI for 64-bit mips chips (like the "x32" ABI for amd64 chips -- both are ABIs which use 32-bit pointers on an otherwise-64-bit system). This error causes far-ranging problems. One of them was particularly difficult to track down: it caused GCC to select 128-bit `long double` types, which is invalid for the mips32 ABI. This isn't noticed until you try to build musl-libc, which is careful to check for these things. Prior to this commit, nix-build . -A pkgsCross.mipsel-linux-gnu.pkgsStatic.hello would fail. With this commit and #170736, it succeeds.
