[gentoo-dev] [PATCH 8/8] virtualx.eclass: Simplify API into single virtx()

[Justin Lecher <jlec@gentoo.org>]

The new API runs all specified arguments to virtx() inside an XFVB,
instead of defining VIRTUALX_COMMAND and running that in virtualmake.

Xemake and Xeconf should be replaced by "virtx emake" and "virtx econf".
