PPC64 has a similar problem.  It wants to do codegen in PIC mode, but  
it doesn't want the JIT to make dyld stubs.  As such, it does 'JIT  
PIC' mode, which is like PIC but doesn't do the extra load to go  
through dyld stubs.

An alternative approach would be to have the JIT synthesize dyld  
stubs, but that takes work to implement and yields slower programs.
