[Build-common-hackers] Bug#487546: cdbs: class/langcore.mk should set CC=gcc if CC is not set

Package: cdbs

class/langcore.mk sets -g -Wall -O2 without checking whether CC can actualy 
process these options. For instance, -g produces output that is partially 
GDB-specific. On most GNU software, autotools perform these check for us and
set CC=gcc autogamically. On other software, CC is often left unset. This is
mostly okay on a Debian system, because the presumption is that CC=gcc, but
we can never be sure of what parallel compilers, etc. someone might run, so
it would be desirable for class/langcore.mk to set CC=gcc is it is unset.
