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.

     4 Attached is a patch to add __attribute__ ((noinline)) to

     5 call_gmon_start.

     6 

     7 Without this patch, the sec script that processed initfini.s removes a

     8 part of inlined call_gmon_start, causing undefined label errors.

     9 

    10 This patch solves the problem by forcing gcc not to inline

    11 call_gmon_start with __attribute__ ((noinline)).

    12 

    13 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
