You can tell valac which C compiler to use by using the --cc argument.
If you prefer, you can have valac simply skip the compilation step
entirely by passing -C. You can get a full list of command line options
either from valac --help, or by reading the valac man page.

The most popular way to build Vala software is probably with autotools,
which will pass -C to vala and handles the compiling and linking just as
in C. Cross compiling Vala which uses an autotools based build system
should be no different than cross compiling C with autotools.
