to deploy existing binary-only components.
We use the `ld-linux.so.2 PROGRAM' trick to force the use of our own
glibc, and set LD_LIBRARY_PATH to point to the required libraries
(X11, Mesa).
Since Mesa is software-only, Q3A is rather slow. I'll have to
figure out how to use the Mesa from XFree86 (X.Org), since it knows
how to use DRI (or at least speak the GLX protocol). Unfortunately
the xlibs people haven't modularised that part of XFree86 yet.
Also, the flag `+set s_initsound 0' has to be passed to Quake to
disable sound, otherwise it segfaults on startup. It doesn't do
this with the normal glibc, which is strange. Maybe it tries to
dynamically load some sound library or something.
