Well, working it is for quite some time. But I had to change the attribute
letters yesterday since they collided with some IA-64 flag (unimplemented
yet in gas).

Anyway, the problem is that invalid section attributes don't generate an
error, but merely a warning.
Commiting as obvious:

	* configure.in (gcc_cv_as_shf_merge): Fix a typo.
	Use --fatal-warnings option for gas.
