qemu with gtk3

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

Trying to build emulators/qemu with the gtk3 option enabled on
NetBSD-current amd64 I get this error:

[2596/6902] Linking target qemu-system-arm
FAILED: qemu-system-arm 
c++ -m64 -mcx16 @qemu-system-arm.rsp

Tried adding devel/gettext-lib bl3 to options.mk to see if made any
difference but it didn't.
