[mythtv] [PATCH] MythTV uClibc support

[Andrew Mahone]

Here's the patch I mentioned before, updated to a current CVS, and
with a minor change - the mntent code in mythmediamonitor.cpp is only
used if __UCLIBC__ is defined, otherwise the original fstab code is
used - my understanding is that Mac OS X lacks mntent functions, so
that this is needed to make mythmediamonitor compile on that platform.

The uclibc-hack.h include has a number of nasty bits intended to force
GCC never to substitute certain commonly-used double-precision math
functions with single-precision versions that don't exist in uClibc's
libm.  I've tested all of the flags that GCC claims to enable with
-Os, and none of them will cause this behavior without -Os.  If
anybody is sufficiently wise regarding GCC to know how this
optimization can be disabled, it would help to make things a good deal
less ugly.

The patch was tested with CVS from last night, and compiled and
functions properly on my uClibc-only xbox, and also compiled (without
using_uclibc enabled) on my glibc-only desktop system.
