MIPS/LD/testsuite: Correct dynamic links with VR4100, VR4300 and VR5000

Correct LD test suite failures with VR4100, VR4300 and VR5000 bare metal
MIPS/ELF targets which do not default to linking with shared libraries,
which leads to link failures like:

.../ld/ld-new: cannot find -lcomm-data
FAIL: Common symbol override test

or:

.../ld/ld-new: attempted static link of dynamic object `tmpdir/pr14170.so'
FAIL: PR ld/14170

removing:

FAIL: Build pr22471b.so
FAIL: Build pr22471
FAIL: Build pr22649-2b.so
FAIL: Build pr22649-2d.so
FAIL: Build pr22150
FAIL: PR ld/14170
FAIL: --gc-sections with __gxx_personality

test failures.
