Right, program-prefix has been dropped.

It tries to use <target>-*, ie. if using --target=m68k-rtems, the tools
need to be called m68k-rtems-*.

program-prefix has never worked correctly.

rtems-4.6.0 supports Canadian-Cross building. In this case, it is not
clear which of the toolchains being involved program-prefix is meant to
be applied to (target, host, build?).

I can't answer this without having seen your sources.

No, though the diffs between 4.5.0 and 4.6.0 BSPs are not "that large",
a BSP's configure.in/configure.ac, bsp_specs, Makefile.am,
wrapup/Makefile.am and <bsp>/<bsp>.cfg in most cases differ sufficiently
to be incompatible.
