[pacman-dev] [PATCH v2] libmakepkg: when stripping split debug symbols, warn on duplicate paths

[Eli Schwartz]

Trying to strip multiple files installed to the same filepath (in
different components of a split package) can produce surprising results
if those files are built using different options. Per FS#63356 this is
not a supported PKGBUILD configuration. Instead, warn about such cases
when producing debug packages.

Fixes FS#63366
