Doom-emacs: Missing character sets during various make installs of brew Emacs

Observed behavior

Been testing doom make on a bunch of emacs builds to see what works with software like chunkwm, and discovered the following errors on this formulae:

Expected behavior

This looks more like the fault of the guy's build leaving some extra stuff in the path, but I'm not smart enough to figure out how to sidestep it or clean it up. Maybe there's a way to find the charsets dependency locally?

Steps to reproduce

• emacs-mac-spacemacs-icon

Cask of a Macport buid, best compatability, won't play nice with Doom:

~/.emacs.d remotes/origin/develop~1
$  make
Warning: arch-dependent data dir '/Users/travis/build/railwaycat/build-macport/emacs-source/tmproot/libexec/em

Emacs will not function correctly without the character map files.

• emacs-mac-spacemacs-icon-snapshot

Similar issue, more Arch-y flavor.

~/.emacs.d remotes/origin/develop~1
$  make

• emacs

Smoothest install by far, with added default open into GUI from CLI with emacs and emacsclient.

• emacs-plus

Same as above but no CLI, but with better decoration.
