[PATCH] Only build Documentation/ when not cross-compiling

[Peter Foley]

Don't build Documentation targets when cross-compiling.
They are only for build testing, and use the host headers and compiler
which can cause cross-compiles to fail.

Turns out this doesn't work if CROSS_COMPILE is set in the environment.
I'll send another version shortly.

It seems there is more interested in cross-compiling Documentation
than I anticipated, so please ignore this as I'll be trying a
different approach.
