[PATCH libX11] config: add -fno-strict-aliasing now that it is out of $CWARNFLAGS

[Gaetan Nadon]

This patch will ensure the modules continues to suppress the
optimization, based on strict aliasing rules, after the option
is removed from $CWARNFLAGS. There is no change in the object
code produced.

There is no attempt to determine if the module should or should not
have such an optimization. A new warning (-Wstrict-aliasing=2)
has been added to the XORG_CWARNFLAGS macro to help  find code
that may interfere with optimization.
