ANDROID_EXTRA_LIBS is not reflective of the kit

Creator has the ability to support extra native libraries on Android. However, because native libraries come in several architectures, these need to be tweaked for each kit (armeabi, armeabi-v7a, x86, etc)

The android NDK supports ANDROID_TARGET_ARCH. When adding native libraries in Creator, rather than just assigning ANDROID_EXTRA_LIBS, equals(ANDROID_TARGET_ARCH, ...) (or contains()) should be placed to surround the ANDROID_EXTRA_LIBS so that the .pro file does not need to be modified for other platforms. Or, the environment variable used directly:

contains(ANDROID_TARGET_ARCH, x86) :
ANDROID_EXTRA LIBS += /home/user/project/x86/libmylib.so
-or-
ANDROID_EXTRA LIBS += /home/user/project/$$ANDROID_TARGET_ARCH/libmylib.so

For the latter, perhaps the path could be scanned from the end for a directory matching the target arch, and replaced with "$$ANDROID_TARGET_ARCH" so that the substitution happens automagically. Perhaps document this as well. Of course, this assumes that qmake is used in a context with ANDROID_TARGET_ARCH set.
