fix-configure.sh

#!/usr/bin/env bash

# This script fixes *.pc files. It removes extra fodder from Libs
# and Libs.private. It is needed because some configure scripts
# cannot handle the extra options in pkg config files. For example,
# Zile fails to find Ncurses because Ncurses uses the following in
# its *.pc file:
#     Libs: -L<path> -Wl,-rpath,<path> -lncurses
# Zile can find the libraries when using:
#     Libs: -L<path> -lncurses
