gnu-pw-mgr 2.7 fails to build on macOS

[Ryan Schmidt]

Hi, gnu-pw-mgr 2.4.2 does build on macOS 10.13.6, but gnu-pw-mgr 2.7 does not; 
the errors are:

As far as I can tell, these are GNU functions that do not exist on macOS.


The configure script checks for one of these:


checking for canonicalize_file_name... no


But the code seems to be trying to use it even though it doesn't exist.
