glibc-2.8's ./configure has an incorrect check for binutils version. In
this case glibc-2.8 was not prepared to recognised binutils-2.2x (IIRC),
and thus its ./configure does not recognise them.

As a rule of thumb, it is highly suggested that one uses versions of the
same /age/. Mixing 'old' versions of a component with a newer version of
another component can be problematic.

Advice: either upgrade to a newer glibc, or downgrade the binutils to a
version that was current at the time glibc-2.8 was released. Ditto for
the compiler and the kernel headers.

Quote of the day:
    Friends don't let friends build toolchains
    with disparate component versions.
