Add new flags CFLAGS_FOR_BUILD and LDFLAGS_FOR_BUILD
In canadian cross build CFLAGS/LDFLAGS may contain flags good
for "host" but not valid for "build". Define new flags. eg.
# flags common to both "host" and "build"
CFLAGS_FOR_BUILD="-O2 -s -Wno-error"
LDFLAGS_FOR_BUILD=
# additional flags for "host"
CFLAGS="$CFLAGS_FOR_BUILD $HOST_CFLAGS"
LDFLAGS="$LDFLAGS_FOR_BUILD $HOST_LDFLAGS"
