libraries to be copied.

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.

This is implemented by moving the source "toolchain/kernel-headers/Config.in" inside the if BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2. * Change the description and help message of the BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in toolchain/external-toolchain/Config.in. In the case of an external toolchain, the semantic of these options is not to enable large file support, IPV6 or RPC (since the toolchain is already compiled, it has been decided previously). Their semantic is to let Buildroot know about the characteristics of the external toolchain being used. As an improvement, we could guess these values automatically: - for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in bits/uClibc_config.h in the libc headers directory. - for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the same file - for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in the same file - for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep -- "--with-float=soft" But I'm not sure how this would be possible, since these values are used at configuration-time by other configuration options, not only at build time.
