Euphoria Ticket #972: When debugging built interpreter cannot display variable values

When using the - - debug flag to build source on Linux/ia32, and then compiling on Linux/ia64 also with the - -debug flag, the variables are invisible to the debugger.

Starting program: /usr/local/src/euphoria/ia64-debug/eui -i /usr/local/src/euphoria/include -D DEBUG  /usr/local/src/euphoria/source/euc.ex -debug -build-dir "/usr/local/src/euphoria/ia64-debug/bind-build"                 -c "/usr/local/src/euphoria/ia64-debug/eu.cfg"                 -o "/usr/local/src/euphoria/ia64-debug/eubind"                 -lib "/usr/local/src/euphoria/ia64-debug/eu.a"                 -makefile -eudir /usr/local/src/euphoria -cflags "-DEX86_64  -m64 -pthread -c -fsigned-char -DEUNIX  -ffast-math   -g3 -O0 -Wall -I/usr/local/src/euphoria/source -I/usr/local/src/euphoria  -DARCH=ix86_64 -DEREL_TYPE="development""                   /usr/local/src/euphoria/source/eubind.ex
