Hi Bill,

I need to look closer at this. Passing all of the EXTRA_CFLAGS as link 
options seems wrong to me as they may not be valid linker options. That 
said I see that in this case we are actually using the C compiler to do 
the linking. But that said, in the saproc case we are also compiling C 
source files at the same time which means that EXTRA_CFLAGS is needed on 
the main command line, not tucked onto the LD flags. And the implication 
here is that cross-compilation of libsaproc has been broken all this 
time for any platform where the default gcc output would be wrong!
