在第二次编译Binutils-2.15.94.0.2.2时,出现了错误,查了好久也没有找到答案.有谁知道了告诉我一声,我的系统是FC3,LFS的版本是6.1
输入
../binutils-2.15.94.0.2.2/configure --prefix=/tools \
    --disable-nls --enable-shared --with-lib-path=/tools/lib

以后,出现信息是

" This package is known to have issues when its default optimization flags (including the -march and -mcpu options) are changed. If any environment variables that override default optimizations have been defined, such as CFLAGS and CXXFLAGS, unset them when building Binutils."

you may get some hints from the passage of lfs-book6.1
