[PATCH 1/2] gdb: Minor cleanup in some gdb.arch/* tests

[Andrew Burgess <andrew.burgess@embecosm.com>]

A small number of tests incorrectly tried to pass -Wa,-g through to
GCC as an extra compile time flag, either to gdb_compile or
prepare_for_testing.

There were two mistakes, first, the 'debug' flag was already being
passed, this will cause GCC to add a suitable -g flag, which should
then be propagated to the assembler.  Secondly, in order to pass
additional compiler flags, the syntax would be
'additional_flags=-Wa,-g'.  As it was, the flag was just being
ignored.

Given that all these tests pass 'debug', and the invalid flag has been
ignored for some time, I'm just removing the flags in this commit.

There should be no change in the test results after this commit.

gdb/testsuite/ChangeLog:

	* gdb.arch/amd64-disp-step-avx.exp: Remove unneeded assembler
	flag option, syntax was wrong anyway.
	* gdb.arch/amd64-disp-step.exp: Likewise.
	* gdb.arch/arm-disp-step.exp: Likewise.
	* gdb.arch/i386-disp-step.exp: Likewise.
	* gdb.arch/sparc64-regs.exp: Likewise.
