I have looked into the vararg tests and did not immediately find
one that could be readily adapted. The best candidate would be
varargs-memv.ll. However this one also checks for something else.
On the other hand, there may be some value in having a simple
dedicated test like vararg-musl.ll.
If anybody can point me to a suitable test, I can make the adaption,
otherwise I would suggest to just keep vararg-musl.ll as it is.
