| Hello. When I try to cross compile libXT 1.2.1 (or any version) for i386, I
| receive:
| 
|| configure:18569: checking whether malloc(0) returns NULL

looks like

https://gitlab.freedesktop.org/xorg/lib/libxt/-/blob/edd70bdfbbd16247e3d9564ca51d864f82626eb7/configure.ac

XORG_CHECK_MALLOC_ZERO

which comes from here:

https://gitlab.freedesktop.org/xorg/util/macros/-/blob/master/xorg-macros.m4.in
https://gitlab.freedesktop.org/xorg/util/macros/-/blob/master/xorg-macros.m4.in#L1370

and as explained here

https://www.gnu.org/software/autoconf/manual/autoconf-2.63/html_node/Runtime.html

it's lacking a third choice on the end of the AC_RUN_IFELSE macro.
Overlooked here:
