pigz, which stands for parallel implementation of gzip, is a fully functional replacement for gzip that exploits multiple processors and multiple cores to the hilt when compressing data. pigz was written by Mark Adler, and uses the zlib and pthread libraries.
This recipe adds pigz as an alternative provider of gzip-native. Pigz is much faster than gzip on multi-core machines.

This needs to be moved to the inner ldflags.patch, and..

this should be copied to there. The patch should also start with an
explanation of what the patch does (in this case it's trivial, but still worth
having in there.)
Thanks,
Paul

Sorry for not picking up on this earlier, but I think this needs to be
PROVIDES_virtclass-native, otherwise the target recipe will also provide gzip-
native.

This is either missing update-alternatives entries or it is missing RREPLACES/RCONFLICTS with gzip/busybox/etc. Or both.

My intention with the patch was to provide a native-only recipe for pigz, to improve distro build speed.
I'm not sure there is much interest in using pigz on target.

But it went in as a regular recipe and hence needs to play well with others.

I thought I made it native-only by only providing gzip-native?
