Merge remote-tracking branch 'remotes/bonzini/configure' into staging
* remotes/bonzini/configure: build: softmmu targets do not have a "main.o" file configure: Disable libtool if -fPIE does not work with it (bug #1257099) block: convert block drivers linked with libs to modules Makefile: introduce common-obj-m and block-obj-m for DSO Makefile: install modules with "make install" module: implement module loading rules.mak: introduce DSO rules darwin: do not use -mdynamic-no-pic block: use per-object cflags and libs rules.mak: allow per object cflags and libs rules.mak: fix $(obj) to a real relative path util: Split out exec_dir from os_find_datadir Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
