You don't have to use AC_RUN_IFELSE. Just ``test $cross_compiling = yes''.
There are cases when cross_compiling = yes, yet you can run the executables,
for example when you have
--build=i686-pc-gnu --host=i386-pc-gnu
or even
--build=i686-pc-gnu --host=i686-gnu
But AC_RUN_IFELSE doesn't help you here, since it doesn't even try to run
the executable when cross_compiling = yes.
If you wanted to be absolutely sure, you'd have to try to run an executable
on your own. But I don't think it's worth it.
Have a nice day,
Stepan
