[lttng-dev] [PATCH URCU] Pass the CC variable to the example Makefiles

[Jérémie Galarneau]

Cross-compilation fails when using the --host configure option
since the cross-compiler is not invoked by the hand-made Makefiles
in doc/examples.

The CC variable must be passed explicitly to ensure the host's
default compiler is not invoked.
