[opkg-utils PATCH] opkg-build: Add support for explicit pigz

[opkg-utils PATCH] opkg-build: Add support for explicit pigz

[Mike Crowe]

From: Mike Crowe <mcrowe@brightsign.biz>

oe-core has stopped[1] installing pigz as gzip. This means that in order to
persuade opkg-build to use pigz it must be specified explicitly. Let's
teach opkg-build to deal with being passed pigz as a compressor. We can't
combine the check for whether -T is required because opkg-build calls both
$compressor and gzip explicitly.

Hi Mike,

Thanks for the patch! Just merged it into master (I updated the man page 
to reflect the new option)
