No big elf parsing, just browsing through some
structures:
OS auxiliary vector (which the kernel has access to)
-> find PT_DYNAMIC program header
-> find DT_DEBUG dyntag
-> find r_debug
-> follow r_debug.
But I definitely agree a user level program would be better than
hacking this in the kernel, which IMO wouldn't be likely accepted
upstream.
