[PATCH libAppleWM] simplify Makefile as per-target compilation flags are not needed

[Gaetan Nadon]

We then do not need the AM_PROG_CC_C_O to detect compiler which
do not accept both -c and -o together.
The macro was missing, but it will no longer be needed.

This setup is only needed when the same source is compiled
multiple times with different compiler options.
