Well, I couldn't fix it with the compiler options. I don't know why
hpc's and Apple's compilers are so different here, but they apparently
are. But I could fix it by googling for recommendations on how to
avoid duplicate symbol errors, which basically involves defining the
thing shared between a bunch of modules (in this case,
"SPMATRIX_UNIQUE_SYMBOL") as extern in the .h file, and defining it
for real in one of the .c files.

I might have broken something else by doing this, but it now installs
out of the box and passes the tests I need it for.

I'm attaching this as a very short patch file.
