tile: add no-op fe*() routines for libc internal use

These avoid having tile generate real calls to the no-op
functions, which then causes linknamespace test failures.

It might make sense to factor all of these out into a common
header that can be shared by tile, microblaze, etc., but for
now just fix the test failures.
