User qemu profiling

- Makefile.target: re-enable profiling for user qemu. It seems profiling was (accidently?) removed by commit 3937 - syscall.c: * add an include to get _mcleanup prototype * add a call to _mcleanup for exit_group in a way similar to what is done for exit (Laurent Desnogues) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5642 c046a42c-6fe2-441c-8c8c-71466251a162
