Improve C++ standard library detection on Android
* configure.ac: Stop relaying --with-ndk-cxx-shared to the
nested invocation of configure.
* build-aux/ndk-build-helper-1.mk (SYSTEM_LIBRARIES):
* build-aux/ndk-build-helper-2.mk (SYSTEM_LIBRARIES): Insert all
of the C++ libraries available on Android.
* configure.ac: Call ndk_LATE and ndk_LATE_EARLY within if
statement at toplevel, averting needless calls to AC_PROG_CXX.
* cross/ndk-build/Makefile.in (NDK_BUILD_CXX_STL)
(NDK_BUILD_CXX_LDFLAGS):
* cross/ndk-build/ndk-build.mk.in (NDK_BUILD_CXX_STL)
(NDK_BUILD_CXX_LDFLAGS): New variables.
* cross/ndk-build/ndk-resolve.mk (NDK_SYSTEM_LIBRARIES):
Introduce several other C++ libraries sometimes present on
Android.
(NDK_SO_EXTRA_FLAGS_$(LOCAL_MODULE)): Insert NDK_BUILD_CXX_STL
when any of these new C++ libraries are requested.
* m4/ndk-build.m4: Completely rewrite C++ compiler and library
detection.
* java/org/gnu/emacs/EmacsNative.java (EmacsNative): Attempt to
load more libraries from static initializer.
* java/INSTALL: Remove obsolete information.
