Subject: [PATCH] Update CMakefile.txt for aarch64 OS
aarch64 architecture is for 64bit OS.
It doesn't allow the 32bit compiler option like -marm -mabi=aapcs-linux -mhard-float -mfloat-abi=hard
If only the architecture is not aarch64, it follows the existing compiler option, otherwise drop unacceptable options.
