Small feature request for 0.5.9

[Arnaud Quette]

I would really need an "addondir" variable in hal.pc to get to exact
path to install the NUT addons...

Something that would act like:
pkg-config --silence-errors --variable=addondir hal
=> /usr/lib/hal/

The same goes for the fdi file. IMHO, this should point the thirdparty
directory, since it's oriented toward external apps.

Since I'm currently finishing the NUT to HAL bridge, I'll need this to
produce some final integration and packages.

thanks,
Arnaud
