Yep, I would start with a "find $extractDir/$extractedSubDir/", grep for 
*.so, and pipe that through sed to replace the directory with 
$targetExtractedDir. That should yield the volume root relative paths of all 
libraries in the archive. Then for each library test whether the directory is 
relevant (system/lib, common/lib, home/config/lib), check whether something 
in the gccX subdirectory is in the way, and create the symlink.

Those can be ignored. For %A/ relative directories the runtime loader only 
looks in the specified directory, not in gccX subdirectories.

Anyway, feel free to just add AddSymlinkToHaikuHybridImage invocations in 
OptionalPackages. If there's only a few of them, a generic solution might be 
unnecessarily complicated. Your decision. :-)
