como atualizar a libc6 no Red Hat Enterprise Linux Server versão 6.6

Estou executando o seguinte erro ao compilar uma compilação e com base em https://askubuntu.com/questions/421642/libc-so-6-version-glibc-2-14-not-found Tentei atualizar a libc usando o yum , brew, apt-get, nenhum deles funcionou para mim .. o que posso fazer? como posso atualizar a libc6?

arm-none-eabi-gcc: /lib64/libc.so.6: version GLIBC_2.14 not found (required by arm-none-eabi-gcc)

1.
[username@machine build]$ sudo yum install libc6
Loaded plugins: security
Setting up Install Process

sudo: brew: command not found

3.
