Did you by any chance mean 2.26 and 2.27 or are you really trying to
use binutils from 1996?

You must mean 2.26 and 2.27.

Well you are allowed to install an older binutils in another location
and set your path.  You can even set your LD_LIBRARY_PATH if you really
also need an older glibc to do it (not idea why that would be needed).

You may have hit this binutils bug: https://sourceware.org/bugzilla/show_bug.cgi?id=19807
Also maybe related: https://bugzilla.kernel.org/show_bug.cgi?id=114671
