Hi!

Well, I rebuild cross-binutils (2.9.1) under Linux (perhaps best to do
that after upgrade system from libc-5.4.46 to glibc-2.1). 

I still left out patch from Mark E. to build GAS as BFD assembler (it
seems that BFD assembler is still broken even after that patch) but I
included patch from Lazlo Molnar to fix problems with strip.

I'm including shell script to build binutils-2.9.1 (should work both
for building native binutils for DJGPP and cross-binutils). Simply throw
this script and binutils-2.9.1.tar.gz in the same directory and run the 
script (tar.exe must be installed and LFN support must be available when 
building native binutils). I didn't include 'make install' as I perefer
to install into temporary directory and copy needed files manually.

Seems that there are no serious problems with cross-binutils (I build
them on i586-pc-linux-gnu host)
