On Android (and probably some other platforms) I now see a compilation error:

terminal-gcc -mandroid -D__ANDROID__ -std=gnu99 -DHAVE_CONFIG_H -I. 
-I../../gltests -I..  -DGNULIB_STRICT_CHECKING=1 -DIN_GNULIB_TESTS=1 -I. 
-I../../gltests -I.. -I../../gltests/.. -I../gllib -I../../gltests/../gllib 
-I/data/data/com.spartacusrex.spartacuside/files/local/include -Wall  
-Wno-error -O2 -c -o test-stddef.o ../../gltests/test-stddef.c
../../gltests/test-stddef.c:23:22: error: stdalign.h: No such file or directory
make[4]: *** [test-stddef.o] Error 1

This patch fixes it. It could already have been done on 2022-09-13, but
is needed now that the 'alignasof' module is used instead of the old,
deprecated 'stdalign' module.
