nanobsd : do not build specific commands

[oOiOo]

I am trying to minimize my nanobsd images (currently less than 90MB - kernel + userland). So I want to remove all unnecessary binaries ( cal, hexdump, less, etc.).

I have specified some flags - src.conf(5) - like

WITHOUT_TELNET=
WITHOUT_GNU=

But is it possible to not build a particular command?

My current solution is to use a script that removes a list of binaries.

cust_remove_unused ()
{
    for u in usr/bin/cal \
        usr/bin/hexdump \
        usr/bin/less \
        usr/bin/foo \
        usr/bin/bar
    do
        rm -f ${NANO_WORLDDIR}/${u}

    done
}

I know 90MB is already small these days, but I like minimal systems
