Use -B for the linker since some architectures use extra start files defined by

This is the issue I was thinking about when we discussed the spec files the
other day. I am wondered if a linker command file could solve this without
reverting to spec files. I thought linker command files could specify these
platform specific start object files and control what happens. I however could
be wrong.
Sorry for the wrong comment in the commit message. The start files are
found by -L, the problem are the CRT begin and end files. You cannot
specify them in linker scripts. I think we already talked about this
when we moved the stuff from bsp_specs to GCC.
In the long run, the GCC defined start files should be provided by GCC. This
is a GCC 11 topic.
It would have been good to discuss this.
Without this patch its not possible to use powerpc BSPs. Now the
rtems-examples build for all BSPs with some ENOMEM exceptions:
