[OpenWrt-Devel] [PATCH][toolchain] Fix missing help text in DEVEL config menu

[Andrew McDonnell]

This patch completes missing help text for some options under CONFIG_DEVEL.

Provides help for BINARY_FOLDER and DOWNLOAD_FOLDER, and reduces ambiguity in
the help for BUILD_SUFFIX with an example.

Patch resend; this time with tab characters fixed and a component (toolchain) specified.
Note, this should will also apply on Barrier Breaker.
