[mythtv] Compile Mythtv on PS3

[Nigel Pearson]

The compile error on cpu_accel.c was
caused by __APPLE__ being defined.
I think the one in cpu_state.c seems to
be due to CONFIG_DARWIN being defined.

I have no idea why these Apple-specific
symbols are being defined for you.

1) Try a #undef CONFIG_DARWIN in either the
libmythmpeg2 config.h, or the top Myth one?

Possible, although from a cursory glance,
those checks only affect tuning?

2) What does /proc/cpuinfo contain?

3) What is in libs/libmyth/mythconfig.h ?

4) We might need to add a block in
configure especially for the PS3.
Does uname -a reveal anything uniquely
PlayStation-ish?

5) Does adding this block help?
