tests/lib/csu, tests/libexec/ld.elf_so: Apply CTFMERGE=: workaround.

The workaround for

by splitting the recipes for ${PROG} and ${PROG}.debug into an
intermediate ${PROG}.link to avoid overwriting ${PROG} inside the
recipe for ${PROG}.debug.

This is kludgey (writing the `.link' suffix into a Makefile isn't
great) but I see only two cases of it so this'll do for now.

tests/lib/csu/Makefile: Use PROGS_CXX, not PROG_CXX.

There are multiple programs here.

Should fix:

Static libraries like libc may overflow the bounds assumed by -fpie.

Main goal here is to test static pies, but let's take advantage of
this to test the same code several ways, since the csu logic has some
differences for static vs dynamic builds too like the ordering of
_libc_init calls.
