Maybe you could rely on the [`basename-lgpl`](https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=modules/basename-lgpl;h=f81898da85e0ecef3018dbd6f0aba5d57ec0703d;hb=HEAD) module from Gnulib?

I'd keep the `.$(gnutls_so)` prefix unless the file is installed in a dedicated directory (e.g., `$(pkglibdir)`?).

You could use the features from the `lib/inih/ini.h` header if we go with this format (I'd rather think it's a bit too much ;-).

We probably need a check on the return value if the path name is too long (e.g., on Nix).
