The description for the --link-module configuration option is as
follows:
$ ./configure --help | grep -A 5 'link-module'
--link-module=LINKED_MODULE
Path to a JS file to be bundled in the binary as a
builtin. This module will be referenced by path
without extension; e.g. /root/x/y.js will be
referenced via require('root/x/y'). Can be used
multiple times
This lead me to think that it was possible to specify a file like this:
$ ./configure --link-module=something.js
$ NODE_DEBUG=mkcodecache make -j8
This will lead to a compilation error as an entry in the source_ map in
node_javascript.cc will end up having an empty string as its key:
source_.emplace("", UnionBytes{_raw, 105});
This will then be used by CodeCacheBuilder when it iterates over the
module ids, which will lead to the following compilation errors:

This commit suggests that passing a single file be allowed by modifying
tools/js2c.py.
