[MPlayer-users] unable to build with march CFLAGS

[Roger Pack]

Hello.  As a note I tried compiling mplayer the other day like this:

$ cd mplayer-checkout-2013-10-02
$ export CFLAGS=-march=core-avx2
$ ./configure && make

The end result was the below (NB that CD'ing into FFmpeg and building
there works ok).  This is with 32-bit Ubuntu (or cross compiling for
mingw-w64 32 bit--same output).
Thank you.
