Unlike other subprojects, these require an overlay directory to include meson rules to build the libraries. The rules are basically lifted from tests/fp/meson.build, with a few changes to create platform.h and publish a dependency. The build defines are passed through a subproject option, and posted back to users of the library via the dependency's compile_args. The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION is roms/SLOF, which is used to build pc-bios/s390-ccw. All other roms submodules are only present to satisfy the license on pre-built firmware blobs. Best reviewed with --color-moved. Reviewed-by: Daniel P. Berrangé <berrange@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
