Ryan Libby 63f93c7e11 rtld-elf: link libcompiler_rt on all architectures
Statically link rtld-elf with libcompiler_rt on all architectures so
that we don't need to try to pick and choose the bits we need from it
for each architecture (we now leave that to the linker).  Compilers may
emit calls to support functions in this library, but because of the use
of the linker flag -nostdlib for rtld's special needs, the library is
not linked as normal.

Previously we had two different solutions.  On some architectures, we
were able to extract reimplementations of the necessary builtin
functions from our special build of libc.  On ARM, we just linked
libcompiler_rt.

This is motivated by the same issue as D26199 and D27665, but should be
a simpler solution that will apply to all architectures.
