generic_x86_arm to match the cuttlefish configuration that includes
neon.

This reverts commit 7de79cbeaf.
Fixed CTS build issue by adding -march=armv7-a in cts/tests/tests/os/jni/Android.mk since the library built here needs/uses instruction (swp) obsolete in ARMv8.

Overwrite TARGET_(2ND_)ARCH_VARIANT as armv8-a if
TARGET_(2ND_)CPU_VARIANT is set to some known armv8-a core like
cortex-a53, cortex-a73, kryo, denver64 etc.
For clang, -march is ignored if -mcpu is set to specific core so this
change doen't impact the objects built for armv7-a-neon/some_armv8_core
since it's treated as armv8-a/some_armv8_core.
Bug: 62895439
Test: Built modified aosp_arm64 with armv8-a as its TARGET_2ND_CPU_ARCH
and generic as its TARGET_2ND_CPU_VARIANT successfully.
"lunch hikey-userdebug; make" and verify TARGET_2ND_ARCH_VARIANT
is overwritten.

On mips64r6 builds, the shell variable ARCH_MIPS_REV6 is not
cleared before compiling 2nd arch parts. This bug is harmless when
2nd arch is mips32r6 but it omits needed mips-specific assembly
files when compiling libagl and libpixelflinger for mips32r1 or r2.
Clearing the variable is impractical. Using TARGET_2ND_ARCH qualifiers
would work, but Arm and x86 use a simpler method with distinct ARCH_ARM
and ARCH_ARM64 symbols. ARCH_MIPS_REV6 is used in two places.
Both controll 32-bit parts only, so neither place needs adjustment.

These are all either recently unused due to the removal of CFLAGS/etc,

The current 32-bit configuration for generic x86_64 targets inherits some
variables (SSE4 support) from the 64-bit configuration, and overrides
the make variables used for other configurations (SSSE3). Ideally, these
would be using different variables, but until then, unify the
configuration for x86_64 targets so that everything is consistent.

Sandy Bridge actually doesn't have all of these options. For example AVX is only

-Wl,--fix-cortex-a8 is a workaround for an Erratum in Cortex-A8
processors. It slightly increases code size and decreases performance,
and there's no point in using it on non-A8 CPUs.
Instead of forcing it unconditionally, use it when targeting
Cortex-A8 or generic armv7-a (which might or might not be A8).

consistent with other x86 architectures.

LPAE indicates better instructions can be used when atomicity guarantees are
needed. However, LPAE's presence isn't advertised by clang/GCC. We fake an
ARM feature to advertise its presence on architectures where it is.
Also, add a TODO documenting that cortex-a15 is not the correct CPU variant
for krait.

Add mips64r6 target and corresponding mips32r6 target.
Defaults remain as mips64r2 and mips32r2.

Use 4.9 mips64el toolchain for both 64- and 32-bit builds.
Tell ld when 32-bit links are required.
Override 4.9's changed defaults for mips floating point
register use, to get same assembler rules as 4.8 and earlier.
Also: drop unused soft-fp build targets, cleanout redundant
compiler options, and remove extraneous Android.mk file.

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.
