    [PR gdb/27614] gdb-add-index fails on symlinks.

    PR 27614 shows that gdb-add-index fails to generate the index when its
    argument is a symlink.

    The following one liner illustrates the reported problem:

            $ echo 'int main(){}'|gcc -g -x c -;ln -s a.out
symlink;gdb-add-index symlink
            gdb-add-index: No index was created for symlink
            gdb-add-index: [Was there no debuginfo? Was there already an
index?]
            $ ls -l
            -rwxr-xr-x 1 25712 Mar 19 23:05 a.out*
            -rw------- 1  8277 Mar 19 23:05 a.out.gdb-index
            lrwxrwxrwx 1     5 Mar 19 23:05 symlink -> a.out*

    GDB generates the .gdb-index file with a name that matches the name of
    the actual program (a.out.gdb-index here), not the symlink that
    references it.  The remaining of the script is looking for a file named
    after the provided argument (would be 'symlink.gdb-index' in our
    example).

    gdb/ChangeLog:

            PR gdb/27614
            * contrib/gdb-add-index.sh: Fix when called with a symlink as an
            argument.

    gdb/testsuite/ChangeLog:

            PR gdb/27614
            * gdb.dwarf2/gdb-add-index-symlink.exp: New test.
