Vim is invoked via the Makefile for various things, so if you're
building with --with-vim-name=gvim the Gnome code gets called.

Sorry, should've been clearer. I mean that the real (from passwd) home
directory is used, and the environment variable is ignored.

Probably, yes. I only noticed this because Gentoo builds are done in a
sandbox that disallows writes outside of the build directory, and the
usual workaround (setting ${HOME} to a temporary directory) weren't
working. No big deal, since we can selectively allow writes or just hack
the Makefile to make a buildvim -> gvim symlink and use that inside the
Makefile instead...
