I had this error yesterday trying to compile ffmpeg.

The issue was with -DPIC -fPIC

The configure line started was:
CFLAGS="-g -O2 -fPIC -DPIC" ./configure --compile-type=debug
--prefix=/usr --enable-lirc --enable-audio-alsa --enable-audio-oss
--enable-audio-jack --enable-dvb --enable-ivtv --enable-firewire
--enable-joystick-menu --enable-opengl-vsync --with-bindings=perl
--enable-opengl-video --enable-ffmpeg-pthreads --enable-vdpau
--enable-xvmc --enable-xvmc-vld --enable-xvmc-pro
--enable-glx-procaddrarb --enable-libfaad --enable-libfaac
--enable-libmp3lame --enable-libxvid --enable-libfftw3 --enable-hdpvr

I changed it to:
 ./configure --compile-type=debug --prefix=/usr --enable-lirc
--enable-audio-alsa --enable-audio-oss --enable-audio-jack
--enable-dvb --enable-ivtv --enable-firewire --enable-joystick-menu
--enable-opengl-vsync --with-bindings=perl --enable-opengl-video
--enable-ffmpeg-pthreads --enable-vdpau  --enable-xvmc
--enable-xvmc-vld --enable-xvmc-pro --enable-glx-procaddrarb
--enable-libfaad --enable-libfaac --enable-libmp3lame --enable-libxvid
--enable-libfftw3 --enable-hdpvr

and it compiled just fine after that.
