Did you tried to pass
-DNO_CLEAN -DNO_KERNELCLEAN -DNO_KERNELCONFIG -DNO_KERNELDEPEND -DNO_KERNELOBJ
options for make universe over the already built tree ?
When I develop, I use
make buildkernel -DNO_KERNELCLEAN -DNO_KERNELCONFIG -DNO_KERNELDEPEND
unless I change config, or add a file, or add a module etc. This
combination gives me seconds for whole kernel and modules rebuild time
when I know that the build metadata, i.e. files participating in the
build, and the build options, did not changed from the latest full
I think that a similar trick should work with make universe, it might be
somewhat more involved to properly pass the directions, may be not. But
it should give the build time in the range of tens of minutes, indeed.
