It does, good catch, thanks.  The configure fragment resp. shell is fine
without, of course, but they are needed once substituted into Makefile.
Fixed locally.

However, this section is only needed on Solaris < 10, which is why I
didn't notice it until I tried an i386-pc-solaris2.9 build.  It's
probably time to remove support for those old Solaris versions in gdb,
too: gcc lost them after 4.9.
