There is no intermediate linkage level in standard C which allows this.
Linkage is either external, or internal.

On some platforms, library mechanisms are more expressive. E.g. ELF
shared libraries on Linux can have cross-translation-unit symbolic
references which are internal (not available for linkage to the
clients which dynamically link the library).

To do this in just a simple program made of .o's, you'd probably have to put
this function into a custom section, and roll a custom linker script.
The symbol is then private because it's in "mysection" or whatever.

If you want to work in a C-like language, but with finer grained namespaces,
you might want to use C++. (Of course, you can't use some C99 and newer
language features.)
