    configure: Use -Werror to check for existence of -no-pie · cbd73bbb
    Ben Gamari authored
    Clang throws a warning instead of an error when it is passed -no-pie,
    
        clang: warning: argument unused during compilation: '-nopie'
        [-Wunused-command-line-argument]
    
    Consequently configure concludes that it supports -no-pie. However, this
    will fail when used with -Werror. The solution is to simply use -Werror
    in the configure check.
    
    Thanks to @goldfire for reporting this.
