Newer versions of the gnu assembler produce a X86_64_PLT32 for
calls. There is a change under review in llvm to do the same, so update
the tests to not depend on it.
We can still produce a R_X86_64_PC32 with ".long foo - .".

Previous error message style:
error: /home/alice/src/bar.c:12: relocation R_X86_64_PLT32 cannot refer to absolute symbol 'answer' defined in /home/alice/src/foo.o
New error message style:
error: relocation R_X86_64_PLT32 cannot refer to absolute symbol: foo
>>> defined in /home/alice/src/foo.o
>>> referenced by bar.c:12 (/home/alice/src/bar.c:12)
>>> /home/alice/src/bar.o:(.text+0x1)

Previously message told us that relocations could
not be used when making shared object. That was
correct because message could appear (and it is expected)
when we linked executable.
Message should have being changed to something
that says we can't use a subset of relocations against shared
symbols.
Patch fixes the text.

Initially we wanted to check that these two relocations are not present when linking DSO because of
possible overflow in runtime. Patch moves them to writable segment in testcases to allow
proper error check to trigger.
Otherwise error message about using dynamic relocations against text segment was shown.

It was reported in PR28020, that lld does not link code which
gold do. But in fact that is expected behavior as we do not
support DT_TEXTREL.
This patch changes error message as it can report about relocations against
text segments exclusively, other dynamic relocations errors can
be handled separately.

These would just crash at runtime.
If we ever decide to support rw text segments this should make it easier
to implement as there is now a single point where we notice the problem.
I have tested this with a freebsd buildworld. It found a non pic
assembly file being linked into a .so,. With that fixed, buildworld
finished.

When R_X86_64_PC32/R_X86_64_32 relocations are
used against preemptible symbol and output is position independent,
error should be generated.
