If gold is enabled as the default linker, it errors trying to link
to our dummy library empty file and this turns off things which should
be present in libstdc++.

For example, _GLIBCXX_HAVE_S_ISREG isn't defined and HAVE_S_ISREG in
libstdc++-v3/config.h isn't set properly.

Instead of just creating an empty file, create an empty elf binary
instead which addresses the issue.
