Add a new distro feature "ptest".

This patch creates a new distro feature "ptest", which creates -ptest
packages containing the test suite of the package for running on the
target. Test files are installed in /usr/lib/<pkg>/ptest.

The patch also includes a change to automake, splitting the "make check"
target into separate steps for building and running the tests.
