2.6.15-rc1-mm2 breaks strace

[Bernhard Rosenkraenzer <bero@arklinux.org>]

2.6.15-rc1-mm2 works nicely here, aside from the artsd stuff someone else 
already reported, and an new issue with strace (last known working: 
2.6.14-mm2)

[bero@localhost bero]$ strace ls
execve("/bin/ls", ["ls"], [/* 33 vars */]) = 0
Segmentation fault
[ls output without any traces beyond execve-ing ls displayed here]

Also interesting:
[bero@localhost bero]$ strace strace ls
execve("/usr/bin/strace", ["strace", "ls"], [/* 20 vars */]) = 0
Segmentation fault
execve("/bin/ls", ["ls"], [/* 20 vars */]) = 0
[ls output without any traces displayed here]
