CLFS embedded is a bit outdated, recently there have been some changes
in uclibc that resulted in breaking the uclibc config, try make
defconfig TARGET=target_arch instead of that sed command, the rm command
is no longer needed, that warning can be ignored. It seems your final
GCC misses --host $CLFS_TARGET in ./configure.
If I were you, I would configure the uclibc manually with make
menuconfig after make defconfig and the sed's, to make sure uclibc
config is correct with respect to arch and cpu configuration.
