This is a HEAD build on a Core2 Duo (i386 & x86_64) MacBook Pro.
Configure Command: `./configure --host=x86_64-apple-darwin --target=x86_64
-apple-darwin`
Configure Summary:
{{{
Configure completed successfully.
Building GHC version : 7.1.20110131

}}}
Build fails with:
{{{
compiler/stage2/build/LibFFI_hsc_make.c:1: error: CPU you selected does
not support x86-64 instruction set
}}}
Workaround: Adding `-march=core2` to the `x86_64-apple-darwin` section of
`aclocal.m4` convinces the compiler that the processor supports i386 and
x86_64.
