No rule to make target `maybe-install-tix', needed by `install-gdb'

[Michael Elizabeth Chastain]

My 'make install' just blew up:

  make[1]: Entering directory `/berman/fsf/_today_/berman/build/target/native/gdb/HEAD/sim'
  make[1]: Leaving directory `/berman/fsf/_today_/berman/build/target/native/gdb/HEAD/sim'
  make: *** No rule to make target `maybe-install-tix', needed by `install-gdb'.  Stop.

This is gdb HEAD checked out on 2003-03-13 07:11:56 UTC.

  target=native, host=i686-pc-linux-gnu, osversion=red-hat-8.0
  gdb=HEAD%20030313, gcc=3.2.2, binutils=2.13.2.1, glibc=2.2.93-5-rh

The fix looks trivial: remove maybe-install-tix from install-gdb.
I'm too tired to give it proper treatment though.

If it's still there tomorrow night then I'll file a real PR.

Could we quiet down the configury changes for a bit unless they fix
regressions from 5.3?
