> what is the motivation to keep it? ;)

Inherited autotools code. I change it only if i see a reason.

> I don't understand your second question.

When i test whether the option is supported by the linker, i do
this by applying it to a non-library binary.
AC_TRY_LINK() creates a tiny C program and links it using $LDFLAGS.
If it fails, vers_libs_test becomes "no" and --version-script= will
not be used.

The question is, whether this test actually has to try linking a
tiny library.

Of course they should not. I will adopt your change upstream.
