Looking at the "-builder" scheme file that is generated for the
derivation, it looks like what I want is simply %outputs, not %build-
outputs.

No, SHARED_MODE=1 means "please also install the DLL" and SHARED_MODE=0
means "please do not install the DLL". Reading the win32/Makefile.gcc,
nothing special is done if SHARED_MODE=0. It is only used in the
install and uninstall targets. I don’t really understand why you would
want to set SHARED_MODE=0 (even weirder to set it as a default) but I
guess it happens.
