(I've ended up debugging an arm target using an x86 gdb so it is still 
useful :-)

I guess we could.  src/configure.in currently disables the ia64-elf 
target because it doesn't build.  A warning message is printed but it is 
burried in amongst all the other autoconf output.

Anyway, I think it is easier in cases such as this, to just let GDB 
built the best it can.   If a warning is really needed then perhaps have 
the OS sniffer detect and report something (Hmm, I just deleted the 
messaging indicating that the OSABI was unknown :-( ).

enjoy,
