Ahh. I wonder if that's intentional? I haven't dug into
the history, so I'm not sure. It seems like an oversight,
as an initial reaction.

It's certainly debatable whether using /path/to/env perl is
better than hard-coding it at build time (forgetting about
the usage of RUNTIME_PREFIX). [Debatable in a friendly
sense, of course.]
As a distribution packager, I prefer to set the path at
build time to help ensure that an end user can't easily
break things by installing a different perl in PATH.
The Fedora build system will munge /path/to/env perl
shebangs to /usr/bin/perl and it won't effect us much.
That may not be true for other distributions and they may
care more if they want to keep using a hard-coded path to
perl. I don't know how it may affects the Windows folks
either, who are further askew from our other, more UNIX-like
targets.
I don't know what the right choice is for upstream Git, it
can easily be argued in either direction. :)
Cheers,
