The symbols exported by perl are determined by makedef.pl 
There is a hunk that starts:

# Symbols that are the public face of the PerlIO layers implementation
# These are in _addition to_ the public face of the abstraction
# and need to be exported to allow XS modules to implement layers
my @layer_syms = qw(
			 PerlIOBase_clearerr
...

Which lists the PerlIO symbols that get exported.
Looks like only one you are using which is missing is PerlIOBase_noop_fail.

So I _think_ all you need to do is add that symbol to the list.

However the whole of makedef.pl could still do with a cleanup - there 
is a lot of "muddle" in there with some synbols having Perl_ prefix 
and others not, and various groups of symbols re-apearing in multiple 
places.
