Win32 does not use PLT/GOT, so this code cannot work.

"Shared library PIC" only applies to linux.  There is no such thing on
windows, as all code is position independent.  You're trying to compile
something specific to ELF systems under win32 which does not use ELF at
all.  So it's a porting problem with GMP if it tries to compile this
code on a non-ELF platform.

It's not a BFD problem, it's a GMP problem.
