[07/25] Specs cleanup: -gline

[Joseph S. Myers]

Two targets have %{gline:%{!g:%{!g0:%{!g1:%{!g2: -g1}}}}} in
CC1_SPEC.  This is not useful or effective to create a -gline option,
since all -g* options are passed to cc1 automatically
(gcc.c:cc1_options) and so -gline will be passed and rejected by cc1
as unknown.  This patch removes those specs.  OK to commit?

2011-01-13  Joseph Myers  <joseph@codesourcery.com>

	* config/microblaze/microblaze.h (CC1_SPEC): Remove -gline spec.
	* config/mips/mips.h (CC1_SPEC): Likewise.
