missing l4exec

[halo.duan]

Hi all
	I check out latest fiasco and l4linux-2.6-env  and built it
successful. but I find l4exec bin  no where. I read Makefile of the
l4/pkg/exec directory find it get no l4exec target(include instead) , so i
change the target to l4exec. It's failed to build.
	so what happened. It need not l4exec any more or something error in
my build environment or binutil.  my system is linux-2.6.15 and gcc version
is 4.0.1


best regards.
