[uClibc] toolchain on OS X

[Bryan Larsen]

I've also been trying to build toolchains on Apple OS X as well as an
i386 Linux box.

On OS X, I have the following additional problems:

1) reliance on GNU tools:

cp -a in Makefiles
the sed script in the the ancient busybox 0.60.4 busybox.sh included
with Snapgear/uClinux only worked with Gnu sed.

2) hardcoded paths checking for tools.

for instance, the toolchain binutils-dependancies target does

if [ ! -x /usr/bin/msgfmt ] ; then ...

I had installed fink's gettext, but it wasn't in /usr/bin

3) strange errors building libfloat

I tried running ranlib as suggested, but that didn't help.

a build without soft floats doesn't require libfloat and worked
sucessfully.
