You can continue to use the arm-elf-tools, but the libc included has a
bug. The easiest way to get around this IMO is to use the uClinux-dist to
build your sources/apps.
It contains updated libraries etc that are used instead of the ones
provided with the compiler. This bug is fixed in the current
versions of the uClinux-dist:
It's a little more work to begin with but will get you the full source
for most of the things you will want in uClinux land,
