Just configure the face to use the bold attribute, and leave all other
attributes emtpy.

This refers to inheritance, which is not directly related to what you
want.

What you want works well for me without doing anything special.  The
`whitespace-line' face is "merged" with the normal font locking, and I
see the colors from syntax highlighting, but in bold for long lines.

I'm not completely sure if that works in older Emacs version.
Anyway, just try it!
