Support for glibc 2.12 in 7.8 RC2

Hi, The 7.8 RC1 status page [1] states RC1 requires glibc 2.15, and that RC2 will support glibc 2.13 to target Debian 7. CentOS 6 packages glibc 2.12 and this will be the glibc version in the CentOS 6 lifetime. Is there a possibility of stretching lower bounded support in RC2 down to glibc 2.12? This would allow all CentOS users using any of the 6.* releases to use 7.8, I think. [1] https://ghc.haskell.org/trac/ghc/wiki/Status/GHC-7.8/RC1 -- Rob
