[oe] [PATCH] Fix compilation error of events.c in ltrace on i386 target

[Guo Hongruan]

Yes, you are right.

In ubuntu-8.04, all PTRACE_EVENT* macroes are defined in  
/usr/include/sys/ptrace.h. The version of glibc in ubuntu 8.04 is 2.7.10.  
But in glibc-2.6.1 of openembedded, sys/ptrace.h does not include  
PTRACE_EVENT* macroes. So I believe it is a bug of glibc-2.6.10 or ltrace.
