  Since the default GCC and binutils versions used by build-many-glibcs.py,
which are GCC 7 branch and binutils 2.29 branch, support static PIE on
x86_64, x32 and i686, this patch adds --enable-static-pie glibc variants
to x86_64, x32 and i686 to get some coverage for static PIE.

Tested with build-many-glibcs.py.

OK for master?

I see

FAIL: glibcs-x86_64-linux-gnu-static-pie check

with both GCC 6 and GCC 7, a linker error building elf/tst-prelink.

This is:

/scratch/jmyers/glibc-bot/install/compilers/x86_64-linux-gnu/lib/gcc/x86_64-glibc-linux-gnu/7.2.1/../../../../x86_64-glibc-linux-gnu/bin/ld: /scratch/jmyers/glibc-bot/build/glibcs/x86_64-linux-gnu-static-pie/glibc/elf/tst-prelink.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

(and the same with GCC 6).
