Porting a C library to a new O/S is not a small task.  Porting glibc is
an exceptionally large job (and I'm not even certain that it's
possible).  You might have more success with ulibc, newlib, or dietlibc
-- but again it's a big job and not one that we've actually tried.
Proper support for the loader (ldd) and for threads (and thread local
storage specifically) are going to be particularly tricky.  Overall, I'd
advise strongly against trying.

You might be better off just porting the bits that you need to QNX
rather than the whole libc.  What bits have you made custom changes to?
