Isaac Chen 0daa78eef4 Build support for 32-bit armv8-a
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.
