The contents of these .pc files just contain the locations of various
directories, some of whose contents are architecture dependent. Although
their contents will vary according to the architecture of the machine
for which they were built, they are just text files so nothing
architecture dependent in themselves.

The only problem I see with that is, as you point out, if machines with
different architectures are mounting their share directory from some
central location; then the contents of the .pc files will be wrong for
some of the machines using them.

Probably is safer.
