There seems to be no (measurable) difference (10.9--11 vs. 11 ns with
`%timeit -c ...`, and the "largest" `.pc` file we have). I only tested
substituting `${SAGE_ROOT}` by `${SAGE_FOO}` though, i.e., on an ''already
"initialized"'' `.pc` file. Might differ with longer patterns (i.e.
paths) to match, and the original file is slightly larger of course.
