f5af850a29 Revert "Revert "Build support for 32-bit armv8-a"" 
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.

Bug: 64964151
Test: lunch aosp_arm64-userdebug; make -j cts
      lunch aosp_x86-userdebug; make -j cts
      lunch aosp_sailfish-userdebug; make -j cts
      lunch aosp_bullhead-userdebug; make -j cts

7de79cbeaf Revert "Build support for 32-bit armv8-a" 
This reverts commit 0daa78eef4.

Reason for revert: Broke the build for some targets (including marlin and angler).

$ make cts
build/core/combo/TARGET_linux-arm.mk:43: kryo is armv8-a.
build/core/combo/TARGET_linux-arm.mk:45: TARGET_2ND_ARCH_VARIANT, armv7-a-neon, ignored! Use armv8-a instead.
[...]

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.
