I think it *should* be possible to build world with /usr/src mounted
noexec.  Typically, buildworld shell scripts are run using 'sh', for
example in sys/conf/kern.post.mk there is:

vers.c: $S/conf/newvers.sh $S/sys/param.h ${SYSTEM_DEP}
        MAKE=${MAKE} sh $S/conf/newvers.sh ${KERN_IDENT}

The same should probably be done for the nvram_map_gen.sh script.
