Update Android port

Browse source 
ImageMagick now builds but does not link yet some of the time.

* INSTALL.android: Document ImageMagick and caveats.
* build-aux/ndk-build-helper-1.mk (NDK_SO_NAMES):
* build-aux/ndk-build-helper-2.mk (NDK_A_NAMES):
* build-aux/ndk-build-helper.mk (TARGET_ARCH_ABI): Define architecture
and don't respect explicitly specified library names.
* configure.ac: Enable ImageMagick and lcms2 on Android.
* cross/ndk-build/ndk-build-shared-library.mk (objname)::($(call
objname,$(LOCAL_MODULE),$(basename
$(1))))::(ALL_OBJECT_FILES$(LOCAL_MODULE)):
* cross/ndk-build/ndk-build-static-library.mk (objname)::($(call
objname,$(LOCAL_MODULE),$(basename $(1)))):
(NDK_CFLAGS, ALL_SOURCE_FILES): Handle sources files which start with
$(LOCAL_PATH).
* cross/ndk-build/ndk-clear-vars.mk: Don't undefine; clear variables
instead.
* m4/ndk-build.m4 (ndk_SEARCH_MODULE): Redirect make stderr to
config.log.xf64

IMAGEMAGICK
There is a third party port of ImageMagick to Android. Unfortunately,
the port also uses its own patched versions of libpng, libjpeg,
libtiff and libwebp, which conflict with those used by Emacs. Its
Makefiles were also written for MS Windows, so you must also apply the
patch at the end of this file.
This file is part of GNU Emacs.
