lbutils: don't set USE_OPENAT and USE_URANDOM
these can be set explicitly in the compiler flags,
e.g.
make CC="cc -DUSE_OPENAT=1 -DUSE_URANDOM=1"
these options, if set to 1, will cause you to use
the code as if it were running on non-linux systems
such as openbsd. of course, some differences will
still exist, but this is useful for portability
testing when compiling on linux.
