Subject: [PATCH] vala.eclass: Define VALAC_FOR_BUILD for Meson when
 cross-compiling

This is also now needed for multilib.

We're assuming that valac will not output architecture-specific code. It
depends on the project, but it generally shouldn't, and even if it did,
we're currently unable to handle that.

This could have been set in meson.eclass instead, but this ensures that
it stays in sync with VALAC.

Closes: https://bugs.gentoo.org/968825
