yep.

ldd --version

yes. needs to be compiled against a 2.2 glibc. and that glibc should
in turn have been compiled against kernel 2.4.

anyway RH7 glibc should be fine.

you can do:

ldd .../the-app

find which libs it links against.

you can strace the app too. if it is LFS aware you probably will see
calls to fstat64(), getdents64(), fcntl64(). if instead you just see
plain old fstat(), getdents(), etc.. then the app needs a recompile.
