- 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.] Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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).
