The -fPIC is included, or am I missing something?

Hmm, very strange. Is this a mips specific bug in binutils?

No, the symbol __gnu_local_gp is generated by GCC.

*All* modules linked into a shared library must be compiled with -fPIC *and* you must not use -mshared.

s/-mshared/-mno-shared/  Better proofreading is in order.

It would appear that these requirements were not met when xptcinvoke_asm_mips.o (which is a member of ../../dist/lib/libxptcmd.a) was compiled.
