[PATCH 1/1] Add wpa_supplicant Makefile target libwpa_ctrl.so

[Jörg Krause]

"make -C wpa_supplicant libwpa_ctrl.so" can now be used to build a shared
library that can be linked with external programs using wpa_ctrl.h. This
makes it easier to create a separate library package that does not
depend in any other hostap.git file other than src/common/wpa_ctrl.h and
the libwpa_ctrl.so built with this new make target.
