Build dvisvgm and kpathsea on macOS

I found that this wouldn't work unless I put the binary at $(kpsewhich -var-value SELFAUTOLOC) and then made a symbolic link to it.

I got this :(¨

+ IFS='
	'
+ PREFIX=/usr/local/dvisvgm
++ kpsewhich -var SELFAUTOLOC
kpsewhich: option `-var' is ambiguous
+ TEX=

-var-value

It worked!
