Commit 558a512 makes libx11 a propagated input, which seemed to be the
right thing.

I added SDL as an input for QEMU.  Now, when run directly, it just fails:

  Could not initialize SDL(No available video device) - exiting

Looking at strace, I found that it actually needed this:

  LD_LIBRARY_PATH=3D$(guix build libxext)/lib qemu-system-x86_64 ...

IOW it dlopen=E2=80=99s libXext by default.  To avoid the trouble, I think =
SDL
should either (1) have libXext in its RUNPATH, or (2) be explicitly
linked against it (which is essentially equivalent.)

WDYT?  Would you like to make that change?

Thanks,
Ludo=E2=80=99.
