I checked a -current build out of the box, source date 20060907 (top
level Makefile).

Citing from the build window:

/usr/local/sources/cur/src/../tools/bin/m68k--netbsdelf-gcc  -m68060
-Wa,-m68030 -Wa,-m68851 -msoft-float -ffreestanding
-fno-zero-initialized-in-bss   -O2 [...] vers.c

How exactly did you manage to build a kernel with
options M68060 but without -m68060?
