Patchwork Add pigz as gzip-native alternative.

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 gzip-native implementation only.

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?

try 'bitbake pigz' :)
