[FR-V, installed] fix crash on missing TLS section

[Alexandre Oliva]

A program containing object files that contained TLS relocations
referencing (ABS+addend) could crash at link time if no TLS symbols
were defined in the executable or shared lib being linked.  Since such
relocations only make sense to access module-local TLS symbols, I
figured it was perfectly legitimate to issue an error message if no
TLS symbols were defined (i.e., no TLS section is present).

This required tweaking a little bit the error handling of another
invalid condition that used to be the only error condition in
_frvfdpic_elf_emit_got_relocs_plt_entries().

While at that, I found out I no longer needed the tests in
FRVFDPIC_SYM_LOCAL to get *ABS*+offset relocations to bind locally in
e.g. #tlsmoff relocations, so I took it out.

Here's the patch I'm checking in.  Tested building a working glibc for
frv-linux-gnu on x86_64-linux-gnu.
