shouldn't experience any changes as the default is the same as before
the feature was implemented. 

To use the feature, the option to configure is --enable-targets={value}.
Valid values are:
  all: build all targets
  host-only: build only the target for the host you're building on
  list: comma separated list with specific targets selected from

Note that for now, x86_64 and x86 are the same. They both enable
building the lib/Target/X86 directory.

I would appreciate it if, on the next reconfigure, people using PowerPC,
Sparc, IA64 and Alpha would test this feature out. In particular, please
validate that:

The default is "all", "host-only" gets your platform correct, and some
combination of specific targets works correctly.

Thanks for all the feedback and lively debate on this.
