[mythtv] Building rpms for master

[John Pilkington]

I now have tag settings that look ok in the rpmfusion specfile, no 
patches, SOURCE_VERSION=v0.28-pre-2163-g2dadc2c.

configure.ep reports
gcc -O2 -g -march=i386 -mtune=i686 -fomit-frame-pointer 
-fno-devirtualize -c -o /tmp/mythtv_conf.6JNoUZd9.o 
/tmp/mythtv_conf.KqnRgfjx.c
cc1: error: unrecognized command line option "-fno-devirtualize"
C compiler test failed.

gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)

uname -r
3.10.54-1.el6.elrepoNONPAE.i686

Any hope?
