[PATCH 3/21] cmake.bbclass: modify construction of compiler flags

[Mark Hatle <mark.hatle@windriver.com>]

From: Joe Slater <jslater@windriver.com>

Use CFLAGS instead of CPPFLAGS for C_FLAGS variants.

When debug optimization is enabled in the local.conf, the debug (-O0) vs
production (-O2) does not change in the builds.  As the CPPFLAGS do not
contain the optimization settings.

Also the CXX_FLAGS are based on CXXFLAGS, so it makes sense to similarly 
set the C_FLAGS based on CFLAGS.
