problem with using shared library of GMP 5.0.1

[Paul Zimmermann]

       Hi,

I'm not sure this is a GMP bug, but I report it since other users might have
hit this problem. When compiling GMP 5.0.1 on a Core 2 with the default
configure, then installing it and using it with say MPFR 3.0.0, I get when
building MPFR:

/usr/bin/ld: /tmp/lib/libgmp.a(realloc.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/tmp/lib/libgmp.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [libmpfr.la] Error 1

If I recompile GMP 5.0.1 with adding -fPIC in CFLAGS, and reinstall it, then
everything works fine.

This problem does not occur with GMP 4.3.2.
