Port to Android 35

* configure.ac: Temporary workaround for Gnulib bug.  Verify
that the provided android.jar corresponds to Android 35, or any
later version.

* cross/ndk-build/Makefile.in (NDK_BUILD_SO_LDFLAGS): New
variable.

* cross/ndk-build/ndk-resolve.mk
(NDK_LOCAL_A_NAMES_$(LOCAL_MODULE)): Define to
NDK_BUILD_SO_LDFLAGS by default to enable building binaries
with support for 16 kb page sizes.

* java/AndroidManifest.xml.in: Target SDK 35.

* java/INSTALL (16KB PAGE SIZES): New section.  Replace
references to Android 34 with 35.

* java/org/gnu/emacs/EmacsActivity.java (onCreate): Restore
pre-SDK 35 inset-relative placement.

* java/org/gnu/emacs/EmacsFillPolygon.java (perform): Suppress
deprecation warnings, and document why.

* m4/ndk-build.m4 (ndk_INIT, ndk_LATE): Check for and enable
toolchain support for 16 KB page sizes, if available.
(ndk_CONFIG_FILES): Export linker options so derived.

* src/conf_post.h [__ANDROID_API__ < 35]: Include system time.h
and redefine timezone_t to rpl_timezone_t, so that the Gnulib
replacement may not conflict with the useless OS type.
