b2ParticleAssembly.neon.s unable to compile under arm64-v8a

[monckey100]

Trying to compile under ARM64-V8a has been unsuccessful...

running these flags:

    QMAKE_CXXFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
    QMAKE_CFLAGS_DEBUG = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
    QMAKE_CXXFLAGS_DEBUG = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp

you get
:-1: error: the clang compiler does not support '-march=armv7-a'

Omitting it you get the same error for cortex-a8, omitting THAT and you get a problem with the neon assembly file. I am able to compile and deploy without those flags for armeabi-v7a which tells me the compiler does not like the assembly file. I have a feeling this is me being inexperienced with android compilers but I was able to compiler the library, and link with the .a

Doing so ran into another issue where the library could not see the Box2DParticleSystem, which led me back to trying to link the static library
