FYI:

-mno-shared appears to be broken on o32 LE for large programs.

I have a large program composed of about 250,000 lines of code in about 
1000 source files (mostly java but with some C and C++ thrown in for 
good measure).  Linking of this program causes the linker to create 
multiple GOTs.

When building with -Wa,-mno-shared there is some as of yet undetermined 
problem with the resulting executable preventing it from running.

Without -Wa,-mno-shared there are no problems.
