gcc: When cross compiling a target gcc, target flags may be used on the host
The original fix worked some of the time, but not on all machines. Fix
this by applying the change in a different way. Following the example of
the existing BUILD_CFLAGS.
Below is the commit message from the original change to help explain why
this is needed:
Configure identifies a number of warning flags (WARN_CFLAGS and
WARN_CXXFLAGS) from the $CC value. The cross compiler may be different
from the host compiler and may not support the same set of flags. This
leads to problems such as:
cc1plus: error: unrecognized command line option "-Wno-narrowing"
cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
Work around this problem by removing the warning flags from the
BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.
