Nope!  The deciding factor is, what operating system (if any) are
you using *on the embedded board*.  If the answer is "none", then
newlib is for you.  If the answer is "linux", then either uclibc
or some version of glibc is for you (and which of those depends on
how much RAM your embedded system has).

I'll be posting a version that builds on cygwin, the fixes were easy.

If you want to use newlib, there's a patch to crosstool that lets
it build newlib instead of glibc; the changed files are in contrib/newlib.
I haven't tried it myself, and it was done a while ago, so it
might be a bit dusty.
