From=20/usr/src/Makefile.inc1:
1137 .if ${TARGET_ARCH} =3D=3D "powerpc64"
1138 KERNCONF?=3D GENERIC64
1139 .else
1140 KERNCONF?=3D GENERIC
1141 .endif
[...]
1149 BUILDKERNELS=3D
1150 INSTALLKERNEL=3D
1151 .if defined(NO_INSTALLKERNEL)
1152 # All of the BUILDKERNELS loops start at index 1.
1153 BUILDKERNELS+=3D dummy
1154 .endif
1155 .for _kernel in ${KERNCONF}
1156 .if exists(${KERNCONFDIR}/${_kernel})
1157 BUILDKERNELS+=3D ${_kernel}
1158 .if empty(INSTALLKERNEL) && !defined(NO_INSTALLKERNEL)
1159 INSTALLKERNEL=3D ${_kernel}
1160 .endif
1161 .endif
1162 .endfor
So setting BUILDKERNELS has no effect.
