the unneeded stuff is the one that defines options to compile bin utils for different platforms. as well as patches and etc that are not mentioned in LFS.
ill be using the tar file from gnu.org for bin utils, without any mods made by fedora.
the LFS suggests these steps to configure and install the binutils packg:
rm -fv etc/standards.info
sed -i.bak '/^INFO/s/standards.info //' etc/Makefile.in
configure --prefix=/usr \
make tooldir=/usr install
cp -v binutils-2.20.1/include/libiberty.h /usr/include
omitted the check part here
so with these steps i need to get 3 packages mentioned in the first post (binutils, binutils-devel,binutils-static)
and that is the problem coz the binutils packg is huge and sorting out files and etc is horrific task and needs you to know what you need from binutils and what not and etc.
anyone who ever had to do a custom-built rpm for binutils or simply with very good knowledge or RPMs would see right away what to cut out
