[PATCH] Tune default DEBUGDIR for NetBSD

[Kamil Rytarowski <n54@gmx.com>]

NetBSD uses a custom debug file directory /usr/libdata/debug
for the basesystem and does not use separate debug files in
pkgsrc (3rd party package collections).

gdb/ChangeLog:

        * configure.ac: Handle NetBSD specific DEBUGDIR.
        * configure: Regenerate.
