[PATCH] Fix mudflap testsuite flags

[Richard Guenther]

It appears that mudflap tries to run its test without optimization
as well by doing

set MUDFLAP_FLAGS [list {} {-static} {-O2} {-O3}]

but it does not consider options pre-pended on each commandline
which includes -O2.  So we happen to run the {-O2} test twice
and the {} test is useless.

Fixed by explicitely using {-O0} everywhere.  I did not touch
-static as it is sufficiently different (even if it includes -O2 as well).

Committed as obvious.

Richard.

	* testsuite/libmudflap.c++/ctors.exp: Explicitely specify -O0.
	* testsuite/libmudflap.c++/c++frags.exp: Likewise.
	* testsuite/libmudflap.cth/cthfrags.exp: Likewise.
	* testsuite/libmudflap.c/cfrags.exp: Likewise.
	* testsuite/libmudflap.c/externs.exp: Likewise.
