I've set it up, for the next release, to have both ABI=64 and ABI=32
for gnu/linux, like on solaris.

ABI=64 uses gcc -m64, ABI=32 uses gcc -m32.  If -m32 doesn't work
we'll assume it's an old gcc (eg. 2.95) and continue with ABI=32.

ABI=64 will be the default, since it gives better gmp speed.  Maybe
the libgmp3 package will have to override that if it stays in 32 bits.
