This is very basical with a C compiler - it requires a C library for the 
target system, in your case
a C library for 'arm-none-linux-gnueabi', whatever you mean with this 
name !   When making
the GCC helper library, 'libgcc*' parts, especially the shared 
'libgcc_s.so', the existing target
C library parts would be required.  This is the expectation in a GCC 
build for a system target,
a target which has the native GCC as its default GCC type. Linux is a 
system target, not an
embedded target which doesn't know a native GCC for it!

If your target name would be something like 'arm-tizen-linux-gnueabi', 
'arm-meego-linux-gnueabi',
'arm-debian-linux-gnueabi' etc., meaning making GCC for some existing 
'arm-linux-gnueabi'
system, then you would know where the "right" pre-made C library, here 
'glibc',  for your target
system would be.  Systems like Tizen, MeeGo and Debian are real and 
existing and even have
native GCCs for them already...

The "right" is the key word because people have very narrow attitudes 
related to this subject,
equivalent to trying to drive with bare wheels without any tyres if they 
yet haven't the RIGHT brand
of tyres for their just bought car!  Maybe you are one of these guys :-(

The simple solution is to accept ANY of the pre-made arm-linux-gnueabi 
systems to give the
required target C library when making your GCC for your own "None" 
system.  And after the
GCC build being succeeded, building your own glibc for your own "None" 
system, replacing
the temporary "only suitable but not ther right" glibc in the 
crosstoolchain!

The hard solution is then that "drive with bare wheels to the tyre shop" 
approach. There are
scripts for these attitude problem people who cannot use a pre-made 
hammer when making
a hammer, a pre-made native GCC when making a native GCC etc.  With 
Google you will
find them...
