[poppler] [PATCH] Make it possible to disable tests building.

[Diego 'Flameeyes' Pettenò]

Most source distributions like Gentoo, FreeBSD's Ports or pkgsrc allow
their users to choose whether to run unit testing or not. When the
user doesn't want to run unit testing, building the tests will just
take time during 'make all' phase for no good reason.

On the other hand, during development, tests can be used to make sure
that the library is still in a state where it can be linked agains, so
disabling them entirely during that phase might not be what is wanted.

This patch adds a configure switch to explicitly disable building of
tests during 'make all', still leaving an option to build them with an
explicit request.
