[cairo] Compile Mac OS X universal binary of cairo

[mpsuzuki at hiroshima-u.ac.jp]

Hi,

If you want to execute ./configure only at once, and start
to build cairo library for multiple architecture with
incompatible endian - you should include Carbon/Carbon.h,
and use macro "TARGET_RT_BIG_ENDIAN" or "TARGET_RT_LITTLE_ENDIAN".
Both macros are set to appropriate value, for each architecture,
automatically. You don't have to refer the value detected by
configure script.

Regards,
mpsuzuki
