Jack Howarth - June 19, 2011, 1:10 a.m.
Since the common config/mh-darwin file doesn't exist on gcc-4_5-branch, the following patch
creates a config/mh-x86-darwin to allow r175089 and r175108 to be effectively backported. This
change is worthwhile to provide darwin11 users access to dragonegg (since dragonegg doesn't
build on gcc 4.6.x yet). Bootstrap and regression tested on x86_64-apple-darwin11. Okay
for gcc-4_5-branch?

	PR target/49461
	* configure.ac:  Use mh-x86-darwin.
	* configure: Regenerate.
	* config/mh-x86-darwin: Add file and pass -no_pie on BOOT_LDFLAGS for darwin11.
