qemu build failure

[Paul Goyette <paul%whooppee.com@localhost>]

With a up-to-date pkgsrc and starting with a newly-created sandbox (from
sysutils/mksandbox), I am getting the following error when building
emulators/qemu

=> Setting PaX MPROTECT flags
paxctl: Can't open `/tmp/pkgs/emulators/qemu/work.x86_64/.destdir/usr/pkg/bin/qemu-system-ppcemb': No such file or directory
*** Error code 1
