scripts/gdb: If not building expat for gdb, disable

--with-expat=yes is unconditionally passed to the gdb configure
stage, instead of respecting the ${do_expat} decision.

Disable if not needed. Prevents error building canadian cross;

configure: error: expat is missing or unusable

Where configure stage fails to find expat on the host compiler.

Set the default behavior on alpha to use -mieee since the large majority of

     6
time we want this (bad/weird things can happen with packages built without
thomas@1461
     7
-mieee).

To satisfy those people who may not want -mieee forced on them all the time,
thomas@1461
    10
we also provide -mno-ieee.
