| 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). |

| 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/. |
