sci-physics/geant-4.9.1_p02 wants to be able to get an openinventor with
USE=openinventor. However, on sparc we must package.use.mask this option
because openinventor will not build. It will not build because its
architecture file (machine.h) does not know about sparc linux (or any
big-endian linux for that matter). With the following little patch,
openinventor will build and install on sparc, and the demos all seem good. I
do not know if everything is correct, however, because this change only matters
in a couple classes (SoInput, SoOutput), and I don't know if the demos hit
them. No attachment because the test patch changes only one line.
