If you could work together and see which patches seem reasonable to
submit upstream that would be appreciated. I cannot guarantee they
will all accepted if they make the code really complicated/broken.
And elfutils really is designed to make use of a full featured libc
like glibc. So if at all possible I would really recommend not using
something like uclibc. But we should do a reasonable attempt to make
sure the fork/difference isn't too big.

We don't really use mtrace() consistently, not all tools call it at
the start. Unless someone disagrees I wouldn't mind just removing them.
There are other ways to track memory usage. I run valgrind regularly
on some of the tools to see whether we have any memory leaks. Although
that isn't automated (it probably should). But neither is it automated
for the mtrace() case.
