Is MACOSX_DEVELOPMENT_TARGET a thing?

[Lawrence Velázquez]

Note that I said "DEVELOPMENT" and not "DEPLOYMENT".

I came across it while reworking perl5.16's patches. I can't tell
whether it's intentional or a mistake, and my extensive research (one
Google search and one DuckDuckGo search) only turned up other references
to Perl builds.

Has anyone heard of this before?
