Subject: [opkg-utils PATCH] opkg-build: Add support for explicit use of pigz
To: opkg-devel@googlegroups.com,
    yocto@yoctoproject.org

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 with the one for
gzip because opkg-build needs to call $compressor and gzip separately
to construct the package.
