xorg-macros.m4.in: use the autoconf cache for XORG_CHECK_MALLOC_ZERO
Improve configure speed by checking the autoconf cache before compiling and
running the test.
As this means cross-compilation environments can trivially seed this cache as
appropriate, remove the cross-compiling value (which for embedded systems using
uclibc is wrong).
