reduce library uses unlink, but the unit tests need to
override it in a specific way.
But linking unit tests with LTO requires the wrapper
definitions be in objects/libraries listed *after*
the object/library that refers to it. So we need to
make the unlink wrapper somewhat generic. We do this
by exporting a string and callback function that the
user can set to enable a user-defined function to be
called when unlink() is called with a specific file
name.
Also revert 3ef6d06 as part of this patch, since we
no longer require the workaround that it implemented.
Fixes issue #1357.
