It takes quite a bit to validate a toolchain (gcc/binutils/libc) before
it is pushed as default preference. Dont use sword to kill a
fly. You could very well backport the one patch and keep using 2.6.1
if you want to upgrade make sure that its stable enough and tested
enough on some common architecuture/machines but as eglibc is default
libc for micro I wouldnt worry too much for glibc as it might not hit
all users of micro.
