Gee sounds like a _perfect_ application of ... autoconf!

This is a cultural artifact (of a monoculture made possible by the
relative dominance of linux in its niche), not a result of using
[In the early days of linux, it was much, _much_ worse, because not only
didn't they use autoconf, they didn't even _try_ to be portable, simply
assumed everything was exactly like the exact linux distribution they
happened to be using.]
Programs that work well with "edit the makefile and define SYS to be
sys-FOO.c" style tend to program to the lowest common denominator,
because doing anything else simply becomes too painful with this style
of portability. This is fine for some apps (and indeed autoconf
supports this sort of thing quite well), but in cases where you _need_
to use more esoteric functionality, it quickly becomes a real pain;
autoconf's emphasis on finer-granularity helps considerably (though it's
always going to be a pain).
The main problem with your argument is that you seem to be looking at
poorly written programs that use autoconf, and jumping to the conclusion
that autoconf is the reason for the poor programming -- it's not. Bad
programmers made a hash of it no matter what style of portability they
