When LOCAL_STRIP_MODULE := keep_symbols is set, then the normal strip rules
will be modified so that only the .debug_* sections are removed. The original
symbol table is left alone.
This allows the compilation of certain libraries so that libbacktrace library
can provide meaningful names to functions.

Now we have enabled arm64 clang.
This change remvoed arm64 clang build warning and cleaned the
arm64 unknow c flags.

I don't think we can realistically turn this on for 32-bit builds any
time soon.
Also, fix the arm64 stack-protector hack.

To ease the transition between toolchains, allow a target to specify
a list of cflags that the toolchain does not support. These will be
filtered out of the cflags provided by the module.
Add TARGET_GLOBAL_UNSUPPORTED_CFLAGS := -fstack-protector for the
aarch64 toolchain, it does not yet suport -fstack-protector.

This should never have been on the default include path.
The NDK statically links its own libthread_db, so I'm removing
bionic's unused copy from devices.

This is the first step to build 32-bit libraries in a 64-bit product.
It will work like this:
1) In the product's BoardConfig.mk, define:
TARGET_2ND_ARCH, TARGET_2ND_ARCH_VARIANT, TARGET_2ND_CPU_VARIANT.
The build system uses those variables to set up an additional compiler
environment for the second arch.
2) When parsing Android.mks, the build system sets up rules to build a
module for both the 1st arch and the 2nd arch, unless it's explicitly
asked to skip so.
Android.mk will be adapted if there is additional rule of generating
source files.
The build system will accept arch-specific LOCAL_ variables, such as
LOCAL_CFLAGS_arm, LOCAL_CFLAGS_armv7-a-neon, LOCAL_CFLAGS_cortex-a15,
LOCAL_CFLAGS_aarch64 etc. Modules use such variables to set up build for
various archs at the same time.
3) Install binary of the 2nd arch by adding "<module_name>:32" to
PRODUCT_PACKAGES. All 2nd-arch libraries linked in by "<module_name>:32"
will be installed automatically.
