Compiling one project just gives me: "avr-gcc: error: unrecognized command line"

gcc version 4.8.2 (GCC)

What could cause this ?
Where can I find "extra" command line parameters

gcc version 4.8.2 (GCC)

How can that be? Arduino includes its own copy of 4.3.3 or so. Use the download from arduino.cc and not some random package that got put together by a clueless linux packaging guru...

Yes, I discovered that the 1.5.0 from Arduino.cc works fine, while 1.5.0 that comes with ubuntu 14.04 is bad.
It's a pity that Arduino does not maintain a .deb package r ubuntu repository - I bet many more people are annoyed by the defective package provided by canonical.
