It's not annoying at all, we use it in strategic places.
For example, see how pypy/rlib/_rffi_stacklet.py implements a
stacklet C library that can be used in RPython.

It uses an "ExternalCompilationInfo" (eci) object:
- separate_module_files lists the .c files you want to compile and link
- separate_module_sources is an easy way to embed C snippets (each source
will create a .c file)

Then you can use rffi.llexternal with "compilation_info=eci"
to declare a function defined in this library.
