Vicente, All,

Not only is it the same logic, but toolchain-external are treated like
all other packages. The fact that _STRIP_COMPONENT did not work for
external toolchains is because the _EXTRACT_CMDS are overriden and
we're not using the "generic" one.

If we did not have the extract commands override, it would have already
been handled.

Thus, adding TOOLCHAIN_EXTERNAL_STRIP_COMPONENTS is only re-instating
the default behaviour.

This should not be needed, as toolchain-external is itself a standard
package. This variable, if not already set, is automatically set to 1
in the generic infra.

So, we have our custom extract commands just to exclude the locale
stuff? And I even reviewed that! ;-)

So, if we had a way to pass those exclude patterns to the generic infra,
we would no longer need to override the extract command. Hmm... But only
two packages (toolchain-external and gcc) need to exclude stuff, so
maybe it is not worth the effort. Thomas?
