I'm sorry I didn't participate in the earlier review threads.  I don't know
what Siddhesh's rationale for that was.  But it's just not the modular
thing to do.  Not every configuration includes every subdir, so things just
break if one subdir always assumes that others exist.

Oy.  Such a fine language, I forget sometimes how wonderful it is.

Whatever you discussed before, this is a straightforward part of the glibc
coding style and you don't get to ignore it for new code.

Actually, the closest analogs we have are things like PERL, which are set
only in configure and config.make.in, and not in Makeconfig.  It's not
hard.  The code also needs to disable stuff when there is no Python binary
available.  But I see we already have benchtests/Makefile doing this
wrongly as your change does.  So just leave what you had for now, and then
we'll clean them up together (by which I mean I will shame Siddhesh into
doing it ;-).

Please do.

That is a nonnegotiable standard for new files added to the source tree.
