Just to note that rather than using cross-files, building i686 on x86_64
should be possible by just setting environment variables.

For example, on Ubuntu 20.04, this works for me:

PKG_CONFIG_LIBDIR=/usr/lib/i386-linux-gnu/pkgconfig CFLAGS='-m32' LDFLAGS='-m32' meson --werror build-32bit
ninja -C build-32bit/

For Fedora or Redhat system the PKG_CONFIG_LIBDIR will be different (I
think just /usr/lib/pkgconfig), but the rest should work identically.
