Add arm64 support
This patch adds `--config=arm64` and `--cpu=arm64` flags for users to
compile for the 64-bit version of the Raspberry Pi.
The existing 32-bit ARM build should still work. This patch only adds
additional 64-bit capabilities. Future patches can remove 32-bit
support.
Eigen needed some tweaks because we have `LDBL_MANT_DIG` of 113 on
arm64. None of the code paths that used the parameters `U` and `V`
actually gets compiled in. Adding `[[maybe_unused]]` fixed the error.
