Vicente Olivert Riera 99122d6780 arch: add support for mips32r6 and mips64r6 variants
- Add support for mips32r6 and mips64r6 target architecture variants
- Disable unsupported gcc versions
- Disable unsupported binutils versions
- Disable unsupported external toolchains
- Disable unsuported C libraries
- Add a hook in order to make glibc compile for MIPS R6.

[Thomas: slightly tweak the glibc hack explanation, to make it
hopefully clearer.]

If your target CPU does not have a Floating Point Unit (FPU)
or a kernel FPU emulator, but you still wish to support
floating point functions, then everything will need to be
compiled with soft floating point support (-msoft-float).
