+	help
+	  If your target CPU does not have a Floating Point Unit (FPU) or a
+	  kernel FPU emulator, but you still wish to support floating point
+	  functions, then everything will need to be compiled with soft
+	  floating point support (-msoft-float).
+
+	  Most people will answer N.

+	help
+	  When using buildroot to build a deployable cross toolchain,
+	  it is handy to include certain target apps with that toolchain
+	  as a convenience.
+	  Examples include ldd, gdbserver, and strace.
+
+	  Answer Y if you want these apps (if built) copied into the
+	  cross toolchain dir under <arch>-linux-uclibc/target_utils/.
