setenv is also less portable: it does not appear in SUSv2, which is still
our baseline spec for Unix platforms.  We've avoided its use since 2001,
cf. ec7ddc158.

It's also fair to wonder how well this change would fly on Windows,
where we have to implement putenv for ourselves to get things to work
right (cf. src/port/win32env.c, which does not offer support for
setenv).

Please stop inventing reasons to change code that's worked fine for
decades.  We have better things to spend our time on.
