[Libguestfs] [PATCH 1/9] Partially fix --disable-erlang

[misc at zarb.org]

From: Michael Scherer <misc at zarb.org>

Without this, configure will always enable erlang, no matter what
argument are passed. Now, we can disable it, even if configure still
need the erlang compiler for some obscure reason.
