  [Driver][FreeBSD] Generalise lib32 handling to support arm

The current code maintains its own list of 32-bit architectures for
which there is a 64-bit FreeBSD architecture that supports it for lib32.
This is unnecessary (if it's not supported, the directory just won't
exist), and means that, when FreeBSD gains lib32 support for a new
architecture, you need an updated toolchain that knows about it.
Instead we can check for any 32-bit architecture and have forwards
compatibility.

This is motivated by FreeBSD adding support for building arm lib32
libraries on aarch64.
