--with-cpu wasn't my suggestion. I was proposing that preconfigure
*detect* the ABI - which is what the compiler specified to configure uses
and can't be further changed by how glibc is configured with other
configure options - and follow the ABI the compiler is using. If you want
the E500 ABI details, configure with a compiler using them; if you don't,
configure with a non-E500 compiler. Just like trying to build a
soft-float glibc with a hard-float compiler or vice versa, things will
only go wrong if glibc is configured inconsistently with the compiler.
