Seems a good plan to me to prune some. Wrt the list:

A nios2 backend *only* exists for gcc 4.1.2. It also needs
binutils_2.17.50.0.12.bb (there is also binutils 2.20.1, but that one
is not fully working yet (and has DP = -1)

For glibc and nios2 I see
glibc/glibc_2.10.1.bb
glibc/glibc_2.5.bb
Not 100% which one is being used. Will peek at it next week.
