The macro unnest-vars is the most important, complicated but hard to track magic in QEMU's build system. Rewrite it in a (hopefully) clearer way, with more comments, to make it easier to understand and maintain. Remove DSO_CFLAGS and module-objs-m that are not used. A bonus fix of this version is, per object variables are properly protected in save-objs and load-objs, before including sub-dir Makefile.objs, just as nested variables are. So the occasional same object name from different directory levels won't step on each other's foot. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
