Define LONG64 if __SIZEOF_LONG__ indicates 64-bit long
All modern compilers (GCC>=4.6, Clang>=3.0) define this macro, so we can
use it to detect 64-bit longs without adding to the architecture list.
This change is needed to successfully run xeyes on a FreeBSD CHERI-RISC-V
QEMU VM via SSH forwarding.
