Ok. If you're not going to change it further, I can do that in the next
days.

> In general, I very much like the approach taken by {{{autoconf}}}, where
instead of having a huge lookup table detailing what version of what OS
supports this function or that function, it actually '''tests''' the
functionality. Overall that seems a far more logical approach to me, and
seems to be what Jeroen is proposing. If we can '''test''' the
functionality of bash, rather than having code that attempts to find a
specific Linux release, then testing seems a better way forward.
Well, autotools, or the scripts their files are built from, have a lot of
knowledge coded into them (like chess programs, or e.g. `gcc`, too), i.e.
they also - at least partially - detect the system and make the choices
based on that.
(And packages using autotools still have `configure` options like `--with-
package-xy=/path/to/package-xy`, `--with-included-package-xy` and `--with-
system-package-xy`, and lots of `--disable-*` and `--enable-*` one
sometimes ''has to'' specify manually. Try e.g. building a "customized"
version of a recent GCC, with dozens of settings also for GMP, MPFR, MPC,
PPL and CLooG, probably other packages like gettext and zlib as well.
Also, GCC does drop support of older platforms, OSs and architectures, due
to a lack of developer resources.)
Feel free to extend Sage's `configure` (which really could do much more,
setting appropriate environment variables [like your famous `CFLAG64`]
etc.)...
But Sage is (also) a distro with many "foreign" packages, not just a
program, and to make things work together, we have to make choices
normally a user would make - manually - for each of Sage's packages.
The user can still fake Sage's readline was already installed such that
Sage will use the system's one, but that requires some more reading and
typing than just issuing `make` (or double-clicking the Makefile). ;-)
Same for other packages.
