    relocatable: Make native .pc files relocatable
    
    The native .pc files currently have hardcoded paths in them meaning each has
    to be relocated at final install time. pkg-config has built in functionality
    to avoid this, namely the pcfiledir variable.
    
    This function translates .pc files to use the variable meaning further
    relocation later is unnecessary.
