FYI: fix for extra6.test failure on Tru64

[Alexandre Duret-Lutz]

I'm committing this.

2002-03-26  Alexandre Duret-Lutz  <address@hidden>

        * tests/extra7.test: New file.
        * tests/Makefile.am: Add it.
        * lib/am/distdir.an (distdir): When a distribuable directory
        exists both in `.' and $(srcdir), merge both directories.  This
        works around a failure of extra6.test on Tru64 reported by
        Nicolas Joly.
