configure: recognize x86_64-x32 and x32

Browse source 
x32 is the internal arch name, but glibc uses x86_64-x32.
there doesn't exist a specific triple for x32 in gcc and binutils.
you're supposed to build your compiler for x86_64 and configure
it with multilib support for "mx32".

however it turns out that using a triple of x86_64-x32 makes
gcc and binutils pick up the right arch (they detect it as x86_64)
and allows us to have a unique triple for cross-compiler toolchains.
