The default required version of binutils has been increased to 2.22

OK.

Yes, though I'll jump in now to remind folks that I have an outstanding patch
to drop the binutils minimum back to 2.21 unless there's a specific need for
2.22 somewhere.  My patch doesn't affect Will's patch, but I thought I'd
mention it anyway :-)

Well, the point of 2.22 was to ensure AVX2 support; otherwise (if the
copyright assignment comes through in time) the libmvec patches may need
an x86_64-specific binutils version check.


Actually, it also seems that 2.22 is required for x32 support, so it's
probably worth just admitting that if 2.22 is the right thing for x86,
the rest of us can just suck it up and use --with-binutils as needed :-)
