You're not dense - the build glue to allow an algorithm to be specified
in a kernel config file doesn't exist. It probably should.

The hacky way to achieve what you want would be to edit
</path/to/src>/sys/conf/files and manually add a line like so below the
cc_newreno.c line:

netinet/cc/cc_<algo>.c          optional inet | inet6

That will compile the module into the kernel, assuming "options INET" or
"options INET6" is in your kernel config file.

Cheers,
Lawrence
