modification is not necessary. Just overriding the XIPDL= 
environment/shell variable would have given you the same effect.

supplying on the build commandline would have given the same result:
 XPIDL="/usr/lib/mozilla-1.7.3/xpidl" ./configure .....your_options.... 
--enable-mozilla
 XPIDL="/usr/lib/mozilla-1.7.3/xpidl" make

configure.in should have autodetected this.

See above.

The detection is probably only done for the MacOS X case. So dig into 
configure.ac and add a check for PPC in there. The VLC team is happy to 
take a patch for this.
