It should not vary by machine.  (Of course it may vary depending on 
Texinfo version.  If there is nondeterminism in makeinfo output, that 
should be fixed there in line with general principles of reproducible 
builds.)

libm-err-tab.pl should not cause the manual to vary by machine, because it 
should always generate output tables that cover all machines.

I don't think that's a meaningful question; I doubt these factual tables 
of errors in libm functions have sufficient expressive content to be 
eligible for copyright.
