default "libc.so.0"
help
Specify the core C shared library found in the external
toolchain. This is required in addition to any other
libraries to be copied.
config BR2_TOOLCHAIN_EXTERNAL_LIBS
string "Libraries to copy from the external toolchain"

help
A space separated list of the shared libraries to be copied
from the external toolchain into the root filesystem. Only
the top-level name is needed, i.e. libc.so, libpthread.so as
the actual shared library symlinked to will be copied also.
config BR2_TOOLCHAIN_EXTERNAL_STRIP
bool
default y
prompt "Strip shared libraries"
help
Strip shared libraries copied from the external toolchain.

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
Optimizations to use when building for the target host.
