Comment (by leif):
Wow, getting more and more inefficient (memory footprint, number of system
calls/filesystem accesses). (W.r.t. reinventing the wheel, we should
probably consider dynamically creating Makefiles to build the Sage
library... ;-) )
You could at least cache the mapping of library names to their (existing,
probably single) pathnames (and reuse them instead of creating hundreds of
copies); if there's a shared library, you don't have to record another
potential static one of the same library -- on *nix at least. Not sure
whether hardcoding the library folders (`SAGE_LOCAL/lib*/`) there makes
sense, or is appropriate.
After all, not relying on (say) timestamps of headers but recompiling and
relinking on every change of a shared library is pretty much against one
of their purposes.

`libFOO.dll` is not the convention used on Windows AFAIK; we may
specialize according to the platform, also avoiding unnecessary calls of
`glob()`.
[[BR]]
Do you want to keep the verbose listing of (lengthy!) dependencies by
default?
[[BR]]
You've renamed the parameter `library_order` to `library_sort_key`, the
docstring of `wrap_create_extension_list()` doesn't yet reflect that
change.
