* gcc-interface/Makefile.in: Import target_cpu, target_vendor,
target_os and their host_ counterparts. Remove host_canonical and
target_cpu_default, unused. Remove local ad-hoc computations of
"host", "targ", "arch", "osys" and "manu". Replace uses of these by
uses of the now imported family, hence back to filters against
canonical values. Remove filters on e500 for target_cpu, expected to
be canonicalized into powerpc. Invert the logic filtering on 64bit
sparc for VxWorks. Simplify the filtering logic for bareboard tools
target pairs, now using straight elf/eabi filters on the target_os
part only.
