Planned in for tomorrow ;)
Finished all other planned tasks so I have some time for that

But I cross-compile for linux only, so especially that one shouldn't
become problematic :P

When the entry point is really missing.
When the entry point is there but there is something weird happening
when jumping to it, or it simply points to a "return -1" stub combined
with a ld-warning, than it's not ld's fault.

It's just a smell ...

A look using `objdump -G /path/to/` should tell us.

A short look into
* binutils-cross-arm/2.32.0-r0/git/ld/testsuite/ld-cris/globsymw1.s
* binutils-cross-arm/2.32.0-r0/git/ld/testsuite/ld-cris/warn3.d
* binutils-cross-arm/2.32.0-r0/git/ld/testsuite/ld-cris/globsymw2.s
* binutils-cross-arm/2.32.0-r0/git/ld/testsuite/ld-cris/warn4.d
confirms the smell ...
