[OE-core] [PATCH] rt-tests: rationalise compiler flags

[Ross Burton]

This recipe uses some convoluted methods to ensure the build is using the right
flags but they don't appear to be needed anymore.

No need to prepend HOST_CC_ARCH/TOOLCHAIN_OPTIONS via CFLAGS as the Makefile
picks up CC from the environment and that includes these options.

No need to append the default CFLAGS as their special options are actually in
CPPFLAGS.
