README has a high-level summary, not full details of every supported ABI

"normal" means "the versions documented in install.texi, node Tools for 
Compilation, as the minimum for building glibc on most architectures".

That node should give comprehensive information on what tool versions are 
needed to build glibc.  If an architecture requires GCC more recent than 
6.2, or binutils more recent than 2.25, that needs to be documented there 
(unless the minimum versions for that architecture are the minimum 
binutils / GCC versions that supported that architecture at all).

An alternative in some cases is increasing the global minimum.  Typically 
the global minimum is a version from a few years ago; if it's been a year 
since the minimum major GCC version for building glibc was last updated, 
it may well be reasonable to propose an architecture-independent increase 
of that version to the next major GCC release, for example.
