Oh right, here /lib/x86_64-linux-gnu/libc.so.6 doesn't have a main (but
does have an entry point set in the ELF header).
and checks that it compiles and links. In C, it should, since there IS a
main function in that file. However, in C++ it is not allowed to call
main and gcc will emit an error when set to strict standards:

I don't know of a better solution, but at least the check for "main"
works for all C libraries.
Well, those two work with the symbols I chose.
