PATCH: Include TOOL_OPTIONS in check-flags

[Matthew Sachs <matthewg at zevils dot com>]

TOOL_OPTIONS are not currently checked by check-flags, which is used  
for e.g. dg-skip-if.  This means that tests which do something like / 
* { dg-skip-if "" { *-*-* } { "-m64" } { "" } } */ will not be  
skipped if -m64 is included via runtest --tool_opts="-m64".

Tested by doing:
	cd gcc/testsuite
	mkdir test.dg
	cp gcc.dg/dg.exp test.dg
	cat > gcc.dg/a.c <<EOF
/* { dg-do compile } */
/* { dg-skip-if "" { *-*-* } { "-m64" } { "" } } */
void foo() {}
EOF
	grep -v dg-skip-if gcc.dg/a.c > gcc.dg/b.c
	/usr/src/dejagnu-1.4.4/runtest --tool gcc --tool_opts="-m64" test.dg/ 
dg.exp
	# Check that both tests pass.
	# Apply patch.
	/usr/src/dejagnu-1.4.4/runtest --tool gcc --tool_opts="-m64" test.dg/ 
dg.exp
	# Check the a is UNSUPPORTED and b is PASS.
	/usr/src/dejagnu-1.4.4/runtest --tool gcc test.dg/dg.exp
	# Check that a and b are both PASS.

OK to commit?  ChangeLog:

2006-06-09  Matthew Sachs  <msachs@apple.com>

	* lib/target-supports-dg.exp (check-flags): Include TOOL_OPTIONS in
	the list of compiler flags; this causes those flags to be checked
	for things like dg-skip-if.
