I don't. On my build machine, mplayer is installed properly in
/usr/bin.

I'm trying to 'install' mplayer, headers and ancillary files into a
cross-compilation tree in preparation for making a distribution
for an ARM-based target machine.

In order to do this properly, I need to leave off the --prefix
directive to prevent leakage of information from my build environment
into the executable, then use DESTDIR to tell make where to place
the compiled images.

All of this works beautifully with the addition of a single character
(question mark) into the configure script. From there it gets copied
into config.mak and is referred to by the Makefile(s).

Rathann indicated that overriding DESTDIR works without the
question mark, but I'm not sure what kind of magic that requires.

The line in config.mak seems pretty un-ambiguous and I don't
know of a way to override it:
	DESTDIR =

I guess that's not entirely true. Right now, I'm overriding it
with the patch I submitted ;)
