glitch in General.pm that causes "make check" to fail on Solaris 8

[Paul Eggert]

I installed this.  Odd that it's never been caught before.  I found
the problem when testing on a Sun-only (no GNU code other than GNU m4
1.4.1) Solaris 8 sparc.

        * lib/Autom4te/General.pm (END): Return correct exit status even
        if unlink succeeds and sets $?.  Needed with Solaris 8's perl 5.00503.
