build: Remove PKGS from Makefile
build: Remove PKGS from Makefile

This is an unused variable that is a simply expanded variable, which
means it is evaluated even if not used. As it is a `$(shell ...)`
command, that command is run every time you run `make`. The command is a
`go list` command which causes the go compiler to fetch dependencies.
This means if you make something simple, the makefile still does a lot
of work.

STOP IT!!!
