I have noticed that one can't configure gcc to default to these.
I've also found various other 32-bit or 64-bit -march= arguments for which
it wasn't possible to configure gcc to default to those.
The x86-64-v* the patch only allows in --with-arch_64=, because otherwise
it fails build miserably - as
./xgcc -B ./ -S -march=x86-64-v2 -m32 test.c
cc1: error: ‘x86-64-v2’ architecture level is only defined for the x86-64 psABI
when building 32-bit multilibs. Even if multilibs are disallowed, I think
the compiler still supports -m32 and so --with-arch_64= seems to be the only
option in which we can support that.

* config.gcc (x86_archs): Add samuel-2, nehemiah, c7 and esther.
(x86_64_archs): Add eden-x2, nano, nano-1000, nano-2000, nano-3000,
nano-x2, eden-x4, nano-x4, x86-64-v2, x86-64-v3 and x86-64-v4.
(i[34567]86-*-* | x86_64-*-*): Only allow x86-64-v* as argument
to --with-arch_64=.
