Add the full crosstool-NG sources to the new repository of its own. You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

GCC uses this name to determine what kind of instructions it can emit
when generating assembly code. This option can be used in conjunction
with or instead of the ARCH_CPU option (above), or a (command-line)
-mcpu= option.
This is the configuration flag --with-arch=XXXX, and the runtime flag
-march=XXX.

This option is very similar to the ARCH_CPU option (above), except
that instead of specifying the actual target processor type, and hence
restricting which instructions can be used, it specifies that GCC should
tune the performance of the code as if the target were of the type
specified in this option, but still choosing the instructions that it
will generate based on the cpu specified by the ARCH_CPU option
(above), or a (command-line) -mcpu= option.

Emit hardware floating point opcodes.
If you've got a processor with a FPU, then you want that.
If your hardware has no FPU, you still can use HW floating point, but
need to compile support for FPU emulation in your kernel. Needless to
say that emulating the FPU is /slooowwwww/...
One situation you'd want HW floating point without a FPU is if you get
binary blobs from different vendors that are compiling this way and
can't (don't wan't to) change.

Do not emit any hardware floating point opcode.
If your processor has no FPU, then you most probably want this, as it
is faster than emulating the FPU in the kernel.
