[Bug bootstrap/43733] bootstrap fails on Solaris 10 x86 with GNU as 2.15 and --with-arch=core2

core2 works fine for bi-arch linux builds, but I'll try your suggestion on
Solaris asap

I assume it will work, but 64bit code will not use the core2 instructions,
which might be suboptimal (I want to use the cpu to the full potential!)

I imagine it's also possible for the same problem to occur using -march=native,
if the processor flags indicate core2 instructions will work.

That said, 2.15 is an ancient gas (even though it's very common on Solaris 10)
so I'm not too worried about this bug being fixed and I agree it's not worth
changing the config docs.
