Targets whose binutils support -shared, but that don't have a shared

succeed at the effective target test for -shared, because it brings
nothing from libc, but tests that rely on -shared and that use bits
from libc, such as g++.dg/lto/pr108772, fail despite requiring the
shared effective target.
Extend the effective target test to bring malloc() from libc, that's
likely to be present in libc and bring a substantial amount of code if
no shared libc is available.
Regstrapped on x86_64-linux-gnu, also tested on aarch64-elf with gcc-13,
where the problem was observed. Ok to install?

* lib/target-supports.exp (check_effective_target_shared):
Check for a static-only libc.
OK
