Ohh I missed that this would mean no AC_CHECK_FUNC checks would work,
because they try to link an executable...
(is it true that AC_CHECK_FUNC would not work?)

Of course such a wrapper would be possible, it could cp /bin/true
a.out or touch a.out. In case of arm-elf-gcc we could just omit
-nostdlib, but would get false positives about tests.

But because of the tests it would not make much sense to do so, right?
So it is better to have dummy entry code I think.
Sorry for my question, was not though-through.
