From d695918f7bd92604e561b6963e4ca9aef83f489b Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 27 May 2022 16:35:56 +0100 Subject: [PATCH] configure: enable cross compilation of vof MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit While container-based cross compilers are not supported, this already makes it possible to build vof on any machine that has an installation of GCC and binutils for 32- or 64-bit PowerPC.
