Hid --enable-isa and instead expose --enable-{sse2,ssse3,aes-ni,altivec}

in the help.

Unfortunately we can't just remove --enable-isa, because for the
callback to work the target list has to already exist, and it only
does by virtue of the default=[] param to the enable-isa setup. We
could just use append_const, except then we can't run on Python 2.4,
and the latest release of RHEL only has 2.4 :(

Rename aes_ni to aes-ni in configuration-speak
