From c7ab84305acde95548c4be0fa308dd1654249903 Mon Sep 17 00:00:00 2001
From: Cody Boone Ferguson <53008573+xexyl@users.noreply.github.com>
Date: Fri, 10 Feb 2023 08:20:02 -0800
Subject: [PATCH] Typo fixes in many Makefiles

In particular the following fixes were made:

    -MKFIFo= mkfifo
    +MKFIFO= mkfifo
    -ZIPGREp= zipgrep
    -ZIPINFo= zipinfo
    +ZIPGREP= zipgrep
    +ZIPINFO= zipinfo

If it's not immediately clear what the problem is the last letter of the
variable names were in lower case.
