Strange that mpn_add_1 should be a problem, it's supposed to be
inlined on gcc.

Sounds like the wrong global symbol prefix got chosen for the asm code
by ./configure.  "nm" on mpn/add.o probably shows __gmpn_add_n where
other files expect ___gmpn_add_n.

This is an underscore system I take it.  You can force that in a
completely clean configure with

        ./configure gmp_cv_check_asm_underscore=yes .....

Don't know why GMP_CHECK_ASM_UNDERSCORE hasn't figured that out for
itself though.  No matter, we're already changing it to actually try
linking with or without an underscore, which should be more reliable.

Doesn't ./config.guess already say athlon?
