  Actually, if I haven't messed up, the workaround method using -r should be
fine for linux too - have you tried it?

  If you actually /needed/ to know, you could find out by $(shell uname) or
some similar variant, but I think the solution I gave should work fine on
linux and cygwin without needing to do anything different between the two.

  Oh, it'll be easier to just show you how.  (Bulding a cross-compiler can be
ever so tricky, but building cross binutils is almost always a breeze):

Step 1:  Download and untar the sources, create a directory for building in.

cd /tmp
tar xfvj binutils-2.17.tar.bz2
mkdir obj

Step 2:  Configure, build and install the sources.

cd obj
../binutils-2.17/configure -v --prefix=/usr/local \
        --target=i686-pc-linux 2>&1 | tee conf.log
make all 2>&1 | tee build.log
make install 2>&1 | tee install.log
[optional] make -k check 2>&1 | tee check.log

Step 3:  Tidy up.

cd ..
rm -rf obj binutils-2.17

  Now all you need to do is make sure you've got /usr/local/bin in your $PATH,
and away you go; set AS to i686-pc-linux-as and LD to i686-pc-linux-ld in your

  I remembered this time!
