gcc-source.inc: set PATH for gnu-configize, not for cd
Setting OE's PATH for the 'cd' command has no real effect.
In the normal case it has no effect for the gnu-configize command
either (since OE's PATH is already set in the context which runs
do_preconfigure) but it may be useful when manually re-running a
failed gnu-configize commandline copied from an error log, etc.
