cross.bbclass: override TARGET_* flags 

Some TARGET_* flags are being exported in bitbake.conf currently, so
they are impacting all the tasks of a cross recipe even they are not
in use at all.

This can lead a lot of churn when the cross sysroot are shared by
machines while they have defined different TARGET_* flags.

And sometimes it even causes "Taskhash mismatch" errors.

Fix it by overriding with BUILD_* flags.
