[arch-general] PKGBUILD weirdness

[Robbie Smith]

I’ve been working on my own fork of luakit, building and installing it 
to test changes, and I’ve come across some weirdness in the PKGBUILD. 
The original luakit-git PKGBUILD[1] has a set of options to pass to make 
to (for example) enable luajit.

I rewrote it to conform with pacman/makepkg 4.1 vcs standards[2], and 
for some reason, if I use an auxiliary variable to store these options, 
the packaging fails. Can anyone shed some light on why this might be so?
