tell a bit more about the names of the binutils that the buildprocess expects

to find during cross compilation. We need to fix the gcc-wrapper to support
cross-compiling. Really, it's not that hard to do, but it needs to be done
correctly :)

+The builder.sh for a cross-compiler. Note that the binutils are prefixed
+with the architecture name, so arm-linux-ld instead of ld, etc. This is
+necessary because when we cross-compile a lot of programs look for these
+tools with these specific names. The standard gcc-wrapper does not take this
+into account yet.
