ARCH = arm
Remove the "platform-" prefix from common shared makefiles This makes it clearer which ones actually are real platforms (chosen automatically or explicitly via "make ARCH=foo") and which ones just are shared helpers.

Allow building plain armeabi binaries for android Building with "make OS=android APP_ABI=armeabi" will produce arm binaries that will conform to the armeabi ABI - not using any features outside of armv5te by default (but still optionally using the NEON functions at runtime if detected - even though such devices should rather use the default armeabi-v7a build).

Support building outside of the source tree This allows building two versions for different architectures at the same time, without the built files clobbering each other. This is very helpful when trying to track down differences between two build configurations. To build outside of the source tree, create the other directory to use for building (either outside of the openh264 directory, or as a subdirectory), enter that directory, and do "make -f path/to/openh264/Makefile".

Check that a working android toolchain was found If the user selects a nonexistent ARCH, previously the call that sets TOOLCHAINPREFIX would set it to contain a long error message, which makes it quite hard to figure out what actually went wrong. Instead check that CXX=$(TOLCHAINPREFIX)g++ actually points to a working executable, and abort immediately if this isn't true.

ifneq ($(CXX),$(wildcard $(CXX)))
Check for $(CXX).exe as well when checking for the android toolchain This fixes building for android on windows. Building for android on windows still requires MSYS for running make, but running the ndk-build of the sample projects from within MSYS doesn't seem to work (the OS variable from the OpenH264 makefile interferes with the host system detection in ndk-build), so one still needs to build it in two steps, first make OS=android ... libopenh264.so, then building the sample projects manually.
