What did you do?

Run gomobile bind -target ios a lib using x/mobile/gl but fails:

gomobile: darwin-x86_64: go build -p=4 -pkgdir=/Users/hajimehoshi/go/pkg/gomobile/pkg_darwin_amd64 -tags="" -buildmode=c-archive -tags=ios -o /var/folders/7t/qw3np69559591s1v0mk5_p1m0000gn/T/gomobile-work-360738871/mobile-amd64.a /var/folders/7t/qw3np69559591s1v0mk5_p1m0000gn/T/gomobile-work-360738871/src/iosbin/main.go failed: exit status 2

It looks like in x/mobile/gl, os_osx is always defined on darwin,amd64 and os_ios is not defined, while gomoible bind -target ios tries to compile a lib with darwin,arm, darwin,arm64 and darwin,amd64.

x/mobile/gl: Fix macro definitions for iOS
0c415a2 
Now `gomobile bind -target ios` tries to compile a lib with
`darwin/arm`, `darwin/arm64`, and `darwin/amd64`. In the last
case, a tag `ios` is always added. In `x/mobile/gl`, the last case
`darwin/arm64` was not considered well and causes a compile error.
This CL fixes this compile error.

Fixes golang/go#16067
