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
available on the higher-end SKUs (not on Celeron G550).

-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).

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.
