Feature request: Add option to link to /usr/local/bin instead or a user defined location

[dragon512]

Expected Behavior

When making an RPM it would be nice to make symlinks to a different path.

Current Behavior

The current behavior is that the user can define link_bin_files = True to make symlinks to the /usr/bin directory. However, this is at times a problem as it conflicts with system values. Being able to create the package and define a different location for the symlinks to be installed such as /usr/local/bin or defined user locations that might already be on the path would be very useful
