It's very complicated, but you don't need to track down the original
commands to resolve this build failure.  The problem is with the
library you are trying to link in:

This error message means that you need to recompile libtrace.a with
-fPIC added to its CFLAGS.  Do that and you shouldn't need to mess
with bash's configure script.

Incidentally, you appear to be building things as root.  Don't do
that.  Complex packages' build scripts often assume that they do _not_
have write privileges over the entire filesystem, and may
catastrophically malfunction.  Only "make install" should ever be run
as root.
