Avoid nonportable `./FILE' instead of `FILE' in test.

[Ralf Wildenhues]

This test failure only showed up with parallel NetBSD make: it doesn't
identify `./FILE' and `FILE', and with serial execution, the library in
question is built before the program linking to it anyway.

Pushed to master and branch-1-10.

Cheers,
Ralf

    Avoid nonportable `./FILE' instead of `FILE' in test.
    
    * tests/libtool3.test: Do not use `$(top_builddir)/sub/libname.la'
    in *_LDADD entry if `$(top_builddir)' is `.'.  Fixes test failure
    with parallel NetBSD make.
