[Pixman] [PATCH] configure: add options to disable demos and tests

[Thomas Petazzoni]

On certain architectures, the functionality of <fenv.h> may not be
available, which prevents building the pixman tests. In order to still
allow building pixman easily on such platforms, this commit adds two
new configure options, --disable-testprogs and --disable-demos, which
can be used to disable building the test and demo programs
respectively.

Of course, by default, tests and demo programs continue to be built,
so that the existing behavior is preserved.
