[Bug 46028] Provide separate debug/symbol info files (.pdb) for 32-bit and 64-bit Wine-Gecko 2.47+ package (unstripped 32-bit 'xul.dll' too large to be mapped)

Great, thanks for testing.

If this usage pattern is common, then we can ship a tar containing only .pdb
files so that there is no need to filter. The way I ended up doing it is a bit
more convenient for using with shared build. You can just extract *-pdb.tar.xz
files into /opt/wine/gecko/ and it should just work without creating copies in
each prefix.

Agreed, it would be interesting.
