[Patch ARM] Fix PR target/81863

This has been in my patch stack for quite some time. The problem here
was that we weren't handling arm_word_relocations in
arm_valid_symbolic_address and is the surest fix for this
for GCC8 and GCC7.

Regression tested on arm-none-linux-gnueabihf . Applying to
trunk and backporting to GCC-7 in a day or so.

regards
Ramana
