I tried what you said, that is adding -nostdlib -L/tools/lib to CFLAGS, but now I can't even configure bash. This is the error message: checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking for emacs... no checking for xemacs... no Beginning configuration for bash-4.0-release for x86_64-pc-linux-gnu checking for x86_64-pc-linux-gnu-gcc... x86_64-pc-linux-gnu-gcc checking for C compiler default output file name... a.out checking whether the C compiler works... configure: error: in `/home/booleandomain/tmp/lfs/sources/bash-build': configure: error: cannot run C compiled programs.
