Yes, that's what I do.  Your other problems can undoubtedly be fixed by using 
the proper combination of environment variables and configure options, though 
these days it's typically not worth the trouble.

It'd be a pain, as LIBOTF_CFLAGS is generated automatically by configure.ac via 
EMACS_CHECK_MODULES via PKG_CHECK_MODULES via pkg-config, but libgif typically 
isn't packaged and so we'd have to do a lot of stuff by hand in configure.ac. 
This what we did ten or twenty years ago but nowadays it's typically not worth 
the trouble.  Builders who care about this and are expert enough can set env 
vars and configure options accordingly, which is about the best that can be 
expected for this messy area.
