There doesn't seem to be any output for the failing test or command here.
The error message comes from
gpc346u4-sources/gcc-3.4.6/intl/configure: { echo "configure: error: installation or configuration problem: C compiler cannot create executables." 1>&2; exit 1; }
So gcc can't write for some reason ...?
That message can have many causes, e.g. the compiler segfaulting or the linker not finding a system library. Without the actual output, there's not really anything to go on.
As an aside, "gcc" is an alias for Clang on OS X nowadays (I think since Xcode 5), but shouldn't be relevant here (since you apparently got past the above stage with Xcode 7).
