Building packages this way is not feasible I think due to interactions between
no-X and X packages. Well, running three bulk builds sequencially
doesn't look like
a good solution to me.

In distbb you can explicitely remove some packages from bulk build,
see distbb.local.mk, for example.
All dependent packages will fail recursively.
If you mark x11-links or/and libX11 this way you'll get what you want.

and then use different URLs to base directory or FILE_NAME from pkg_summary(5)
for downloading? Not a big problem.

JFYI.

Packags managers can use this this field and FILE_NAME for switching between
pkgsrc and native X packages.

But I think that it would be better to convert multivariant packages,
X11_TYPE, EMACS_TYPE
and some others to pkg options framework somehow and use single field
PKG_OPTIONS from pkg_summary(5) for this purpose.
