Currently ppc64 and x86 are mentioned as architectures where a 65536 value
is reasonable but arm64 isn't listed and it is also a 64-bit architecture.
The help text says that for "arm" the value should be no higher than 32768
but it's only talking about 32-bit ARM. Adding arm64 to the above list
can make this more clear and avoid confusing users who may think that the
32k limit would also apply to 64-bit ARM.

a value of 65536 is reasonable and should cause no problems.
On arm and other archs it should not be higher than 32768.
