ARCH = arm
Fix building android on x86 In 70360cb11, the ASM variable was moved to the x86-common file even though the android build file didn't include neither platform-arch.mk nor platform-x86-common.mk. Instead of explicitly declaring ASM here, include platform-arch.mk and remove setting of the flags that platform-arch.mk sets. This is inspired by and based on a patch by Licai Guo.

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).

Don't define MACOS and LINUX Nothing within the library actually uses these defines for anything any more. If necessary, the built-in defines __APPLE__ and __linux__ can be used instead of these manually added defines. This is similar to how we use _WIN32 instead of manually defining WIN32.

Also remove an unnecessary step of cd ../../../.. at the end - since all make commands are run in a subshell, we don't need to restore the current working directory afterwards.
