    localedata: Do not generate output if warnings were present.
    
    With LC_MONETARY parsing fixed we can now generate locales
    without forcing output with '-c'.
    
    Removing '-c' from localedef invocation is the equivalent of
    using -Werror for localedef.  The glibc locale sources should
    always be clean and free from warnings.
    
    We remove '-c' from both test locale generation and the targets
    used for installing locales e.g. install-locale-archive, and
    install-locale-files.
    
    Tested on x86_64 and i686 without regressions.
    Tested with install-locale-archive target.
    Tested with install-locale-files target.
