I don't think any third-party softwares expect it to be a broken symlink
either. Current installincludes does something equivalent to the following:

# mkdir /usr/include/pccard
# ln -s bus/pccard pccard

This creates the symlink *inside* the /usr/include/pccard, that is,
/usr/include/pccard/pccard -> bus/pccard. My patch was supposed to avoid
the mkdir above, so that grep -r foobarbaz /usr/include does not print
error message.
