The BR2_USE_SSP option is only used inside the uClibc build, so only meaningful for Buildroot internal toolchains. Therefore, the option is moved to the right location so that it isn't visible when working with external toolchains.

Setting this option will enable the "-mfpu=vfp" option.
|

If your ARM CPU has a Vector Floating Point Unit (VFP)
|
|
and the toolchain supports the option, then the

code can be optimized.

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/.
