[arch-dev-public] RFC: go-pie removal in favour of GOFLAGS

[Morten Linderud]

Yo!

After another few lazy weeks I have finished up the new Go packaging guidelines.

https://wiki.archlinux.org/index.php/User:Foxboron/Go_packaging_guidelines#Flags_and_build_options

The changes that has been done since last time is some structing of the page,
added a list explaining all the flags that have been added to `GOFLAGS`, and the
addition of `-mod=readonly`. 

The intention of adding this flag is to prevent Makefiles or build systems to
silently modify the lockfile of the source code after checkout. This is
to ensure reproducible build.

If there are no objections, I'll probably merge the guidelines this weekend
section-by-section to make the wiki admins happy. The new package should land
sometime nextweek.

At the end of the month I'll make a todo with the remaining packages depending
on `go-pie`.

The complete future Go PKGBUILD is attached to this email below.
