Host gtests that don't use pthreads themselves need to be linked

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.)

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.

Enable incremental builder to find files that moved, and try to process them via patch + rename, instead of delete + add.
This patch completes the support for AArch64. It adds the last few
tweaks that will enable a AArch64 build of bionic.
Please note that though AArch64 uses the new kernel infrastructure,
where the userspace exported headers live in uapi folders, we still
need to include "kernel/common" in the include search path
(take a look at external/kernel-headers/uapi/asm-generic/signal-defs.h).
Also remove the relro linker flags for now as they crash the foundation
model.

a warning whenever we created a shared library with a text
relocation. At the time, we wrote:
=====
Emit a warning when the static linker detects a shared library
has text relocations. Text relocations make it harder to
share pages across processes, and make it harder to use
certain memory protection features in, for example, SELinux.
This warning will turn into an error in a future change
(via --fatal-warnings)
=====
All code which uses text relocations has either been fixed, or
we've temporarily worked around the issue so the code can still
compile.

With this change, you can install a shared library with module name foo
as bar.so to the system.img with:
LOCAL_INSTALLED_MODULE_STEM := bar.so
Note that we in general still disallow a static/shared library to
specify LOCAL_MODULE_STEM or LOCAL_BUILT_MODULE_STEM, because the build
system uses LOCAL_MODULE to compute build time dependencies, such as
export_includes, the -l linker flag etc.
Also, if you use LOCAL_INSTALLED_MODULE_STEM to change the installed
file name and if any other module links against this library, you may
run into runtime error: the library name baked in to the binary is not
the same as file name in the system image.
