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.

|

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/.
