building gdb with newer clangs on 10.7 and Xcode <4.4

[Gagan Sidhu]

it’s the scripts or macro check for xcrun are causing a problem:

if i edit this file to just leave the ‘else’ exec, then the gdb configuration process goes fine.

i didn’t create a bug ticket since i am not sure if these scripts are still supposed to be here, as i have noticed others previously discussing 17664:
