ANDROID_BUILD_TOP variable is being deprecated and thus all paths are assumed to be relative to the top directory. However, this is causing problem when some of the paths are constructed in the Android build system and used in the non-Android makefiles that are usually executed NOT at the top directory but at a sub directory using -C option. As a result, the relative path from the Android build system become invalid in the non-Android makefiles. In order to overcome the restriction, ANDROID_BUILD_TOP is manually constructed when invoking the non-Android makefiles by using $$(pwd). The non-Android makefiles are expected to construct the absolute path by prepending ANDROID_BUILD_TOP to any path that came from the Android build system. Specifically, Kbuild is modified so that ANDROID_BUILD_TOP is prepended to WLAN_ROOT and WLAN_COMMON_INC to make them absolute paths.
