Current evaluation

Staged .pc files get prefix rewritten to $SNAPCRAFT_STAGE plus the original configure prefix, producing invalid paths when an alternate --prefix was used. Open since 2018, no labels or comments; pkg-config prefix handling has since been reworked in the codebase.

Suggested action: needs triage

Reason: The issue is a genuine bug report (invalid prefix in staged pkg-config files) with zero maintainer interaction, no labels, and no comments in 3015 days, so it has never been triaged. Git history shows the pkg-config prefix handling was reworked (e.g. 'fix: don't modify prefix for relocatable pkg-config files (#5157)' and 'fix_pkg_config removes prefixes from staged snap's .pc files (#3848)'), suggesting the behavior may have changed, but I could not confirm whether this exact alternate-prefix case is fixed, so a maintainer should verify before closing.

Issue body

The prefix variable of the pkg-config file is currently changed to `$SNAPCRAFT_STAGE$originally_configured_prefix_dir` by snapcraft when staging, and the value is not valid. ``` $ cat stage/lib/pkgconfig/hunspell.pc prefix=/home/ubuntu/poedit/stage/snap/poedit/current exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include Name: hunspell Description: Hunspell spellchecking library Version: 1.3.4 Libs: -L${libdir} -lhunspell-1.3 Cflags: -I${includedir}/hunspell ```
