Using american fuzzy lop has found a lot of issues. It would be nice
make using it a bit easier. Our build files make sure that no shared

Now CC=afl-gcc ./configure --disable-textrelcheck will allow them so
that afl can instrument the libraries.
Don't try to use or install them except with afl-fuzz. When selinux is
enabled it might prevent loading the libraries with DT_TEXTREL set.
I pushed this to elfutils git master now. Running on 32bit x86 Fedora
has discovered some more crashers. I am currently analyzing and will
post patches soon.
