[Qemu-devel] [PATCH V15 3/9] libqblock: build: add rule for libqblock.la

[Wenchao Xia]

  Now libqblock.la can be built with neccessary object files,
and can be automatically cleaned by make clean in root directory.
make libqblock-clean also clean it. -fvisibility=hidden was used
to hide symbols, and a special macro was introduced to export
symbols that marked as public.
