Hi,

While using @progbits in .pushsection work on some targets, it does not
work on arm target where this introduces a comment. This patch replaces
its use in gdb.dlang/watch-loc.c by %progbits which should work on all
targets since it is used in target-independent elf/section7.s GAS test.

ChangeLog entry is as follows:

*** gdb/testsuite/ChangeLog ***

2018-03-01  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* gdb.dlang/watch-loc.c: Use %progbits instead of @progbits.

Is this ok for master?

Best regards,

Thomas
