This extra 'depends on' should be repeated on the comment about
toolchain options below, so that this comment is only visible when the
actual package is visible.
Have a look at http://buildroot.uclibc.org/downloads/manual/manual.html#dependencies-target-toolchain-options

(Note: you don't have to repeat the "# ARG GCC doesn't support ..." on
the comment)

Best regards,
Thomas
