include/version.h: workaround sysroot inc order

On some systems the host system or even the cross sysroot can
contain a version.h.  This leads to the wrong file being picked
up and a PLAIN_VERSION undefined error.

This workaround symlinks the version.h into the tool folder to
allow reordering of search folders.
