For what purpose?  If you are using modules, they are already in one
global namespace, the various roots of which are in the %load-path
and/or %load-compiled-path.  (resolve-module '(foo bar)) should work
regardless of what file calls it.

Perhaps you are interested in `load', which is problematic regarding
compiled files; for example when loading from a compiled file, how will
`load' know what is the current directory?  Note that .go files are
installed to e.g. /usr/lib64/guile, while source is in /usr/share/guile.

My suggestion is to use modules by name, or, equivalently, to use
`load-from-path'.  There might be a "proper" solution here, but I
haven't found it yet.
