I've been able to get the current meson in OI to do both 32 and 64 bit
builds without any real trouble.  Most of the 32 & 64 work that Aurélien
and Michal had previously done for these packages still applies and has
continued to work with meson & ninja. The issue for this one package starts
when it calls out to qmake, for Qt.  That's its own separate build system.

I'm sure that if I knew more about Qt and qmake I could set a combination
of PATH.32, PATH.64, CFLAGS.32, CFLAGS.64 and probably additional settings
to eventually get qmake to behave.  I don't think it's worth doing in this
case though; having the base set of gstreamer1 plugins depend upon Qt5
for some tiny bit of extra functionality isn't worth it.

I don't personally think meson is any real improvement over autotools,
but it's supplanted autotools in most of the GNOME stuff so I'm trying to
learn it well enough to get by.
