Intelligent handling of legacy PKG_CONFIG_PATH dirs
Intelligent handling of legacy PKG_CONFIG_PATH dirs

If the feed tries to add a directory under 'lib' or 'usr/lib' to
$PKG_CONFIG_PATH, and the directory doesn't exist, use the corresponding
'lib64' directory instead, if present. This is for existing RPMs which use a
different directory structure for different architectures.
