Fix build/17104

Browse source 
This patch is to fix the build error when GDB is configured as:

  CFLAGS=-Wall ./configure --with-babeltrace; make

This patch adds one line of code in configure test to use local
variable 'pos'.

Note that we append -Werror to CFLAGS to catch the warning related to
assignment to scope.  See more in this thread
