The arm_neon.h file is properly copied to the right place bu the build script,
and inserting a #error in there did cause my build to fail, so I think I have
the right one.
I am setting up my Linux VM to rebuild arm-linux-androideabi-gcc to check if it
behaves the same as the Mac-built version does.
Thanks a lot for your help in sorting this out.
Best Regards,
