platforms: document precedence rules for TARGET_EXTRA_*FLAGS
scripts/wrapper/libwrapper.sh adds these global options before the rest
of its command line, so later options from the package's build system
will overwrite them. Document this fact in case anybody wonders why
these options cannot be used to overwrite the default passed by the
package.
