Hello,
attached please find a cosmetic change to the test definitions
for AC_CHECK_{ALIGNOF,SIZEOF}.
OK to commit?

* tests/local.at (AT_CHECK_MACRO_CROSS): New macro, creates two tests:
the first one is usual AT_CHECK_MACRO test, the second one checks
that the same works when cross-compiling.
* tests/semantics.at (AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF): Use it.
