commit 22b778e6ea951774df921a2a49c0cf75a2b512a3
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Wed Jan 5 22:23:19 2022 -0500

    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.
