request for qthreads to install a pkg-config .pc file

[mppf]

Over on the Chapel project we are trying to use pkg-config .pc files from the bundled third-party dependencies instead of libtool .la files. The reason we are doing this is that many package managers don't install .la files at all (see e.g. https://archlinux.org/news/operation-libtool-slay-in-testing/ ) and we are working towards having Chapel packages for more OSes. Today, the qthreads build produces a .la file. This is a request for the qthreads build/install to also produce a .pc file.

I do not have much experience generating .pc files but the file format is pretty simple. https://lists.freedesktop.org/archives/pkg-config/2007-August/000219.html has some suggestions for how to do it in an autotools project and https://people.freedesktop.org/~dbn/pkg-config-guide.html#writing has some documentation about what to put in the .pc file. Of course you might find better resources in your own investigation.

Hi @mppf. I wanted to ack this request for now to let you know I've seen it, since it is vacation season for my team -- @janciesko is out currently and I'll be out most of the next two weeks. I read through the corresponding Chapel github issue to get some context just now, but we will need some time to look at the pkg-config generation documentation and assess.
