Here's a (pretty minimal) fix for branch-1-5.  OK?

I don't have access to a 64-bit sparc system with GNU ld.  Can anybody
confirm that `-m elf64_sparc' is the correct thing to add?  (Without
confirmation I'll leave the GNU ld case empty before committing.)

Cheers,
Ralf

        * libtool.m4 (_LT_AC_LOCK) [ solaris ]: Add `-64' to $LD if
        necessary, to permit combining of several convenience libs
        without any further objects added.
