The answer is staring you in the face:
If you wish to build a custom kernel with native build tools (in other
words the versions installed on your system as opposed to the versions
in the source tree you've synced to) you can do it by using the
nativekernel target.

# make KERNCONF=SYNERGY nativekernel
