-	  If your target CPU does not have a Floating Point Unit (FPU) or a

-	  functions, then everything will need to be compiled with soft
-	  floating point support (-msoft-float).

-	  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.
+	  Select whether to use the toolchain built by the buildroot
+	  system or an external pre-built toolchain.
 
-	  Answer Y if you want these apps (if built) copied into the
-	  cross toolchain dir under <arch>-linux-uclibc/target_utils/.
