Allow other languages to change long double format.

With Fortran adding support for changing the long double format, this
patch removes the code that only allowed C/C++ to change the long double
format for GLIBC 2.32 and later without a warning.

	* config/rs6000/rs6000.c (rs6000_option_override_internal): Remove
	checks for only C/C++ front ends before allowing the long double
	format to change without a warning.
