Are you sure?:

armv8hl has the following options for GCC:

"--with-arch=armv7-a --with-float=hard --with-fpu=neon
--with-tune=cortex-a8"

meanwhile armv7hl was:

"--with-arch=armv7-a --with-float=hard --with-fpu=neon"

'armv8hl' is like "it can run on the armv7-a but armv8-a has the honor".

This is confusing, so.. only 64bit is capable of armv8-a?.
