Users of ARCH_ARM_* defines don't care about first vs. second arch,
set ARCH_ARM_* regardless of which arch is arm.

2ND_TARGET_DEPENDENCIES_ON_SHARED_LIBRARIES was not set,
which was causing the later += to act like = instead of
:=, and the dependencies would disappear as soon as
LOCAL_MODULE was cleared.

For whatever reason, two modules may have the same file as their
installed module. In that case circular dependency is created if the two
modules have requited-by relation.

Host gtests that don't use pthreads themselves need to be linked
against libpthread because gtest itself uses pthreads to ensure
thread-safety. (It can't know in advance whether the code under
test is going to spin up threads, so it has to be pessimistic.)

arm and arm64 have distinct headers, but mips and mip64, and x86 and x86_64
use headers that work for both widths. So where arm/arm64 need to handle the
second architecture case specially, all we need to do for the others is
hard-code the name. (x86_64.mk already hard-codes x86; we need to change
x86.mk for the case where we're building the 32-bit binaries for a mixed
system. mips64.mk doesn't exist yet, but when it does, it'll hard-code
just plain "mips" too.)

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.

Allow modules to generate source into $OUT/gen, which will then
be copied into $OUT/obj and $OUT/obj_$(TARGET_2ND_ARCH) as
necessary. This allows a single build rule invocation that includes
generated source to build for the first and second architectures.
Modules will need to change calls to local-intermediates-dir into
local-generated-sources-dir.

Using LOCAL_MODULE_PATH in a shared library module while building a
multiarch target will cause build rules for both architectures to install
into the same path. Warn and suggest LOCAL_MODULE_RELATIVE_PATH.
Change-Id: I16208ccada6d43a26a342af35096f49d8df26e81
Most users of LOCAL_MODULE_PATH are setting a subdirectory of the
normal install path, for example to install HALs into system/lib/hw.
This is problematic for multiarch builds, where the install location
depends on the arch. Allow modules to specify LOCAL_MODULE_RELATIVE_PATH.
HALs will generally use:
LOCAL_MODULE_RELATIVE_PATH := hw

We have no rigorous way to detect whether the code referenced for this
mechanism changes in between builds. So declare this as a phony target
so that it is rebuilt every time.

Compiling for arm requires using the arm kernel headers and not
the aarch64 kernel headers. Add $(combo_2nd_arch_prefix) to get
asm-$(TARGET_2ND_ARCH) when arm is the 2nd arch.

With those variables, you can set up different values for TARGET_ARCH
and TARGET_2ND_ARCH.
Also fixed a couple of variables.

Intermediate fils of libfoo of the 2nd arch will be built into

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.

PRODUCT_COPY_FILES entries can include the src:dest:owner
syntax versus src:dest. This causes the filter to miss
certain cases. Instead use the word-colon function to
grab the dest regardless of syntax.
