In order to let truss(8) support tracing of 32-bit CloudABI applications, we need to add a new ABI type to libsysdecode. We can reuse the existing errno mapping table. Also link in the cloudabi32 system call table to translate system call names. While there, remove all of the architecture ifdefs. There are not needed, as the CloudABI data types and system call tables build fine on any architecture. Building this unconditionally will make it easier to do tracing for different compat modes, emulation, etc. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D13516
