config error file attached for reference

I am trying to compile gst-ffmpeg for armv7 with arm optimization. I have
validated vfp and neon optimization configuration on FFmpeg. However, when I
pass these exact config elements through gst-ffmpeg, FFmpeg configure fails.
config.err shows extra quotes added to cflags which is obviously not recognized
by the compiler. 

Validated on FFmpeg alone (ffmpeg/configure):
--extra-cflags='-march=armv7-a -mfpu=neon -mfloat-abi=softfp' 

gst-ffmpeg extra configuration (gst-ffmpeg-0.10.11/configure):
--with-ffmpeg-extra-configure="--disable-gpl --disable-postproc
--extra-cflags='-mfpu=neon -mfloat-abi=softfp'"
--->
Resultant config parameters on FFmpeg
(gst-ffmpeg-0.10.11/gst-libs/ext/ffmpeg/config.err- attached):
 --extra-cflags=''\''-mfpu=neon' -mfloat-abi='softfp'\'''

I shall look into this in more detail, but any inputs are highly appreciated.

Also, I think passing in --enable-gpl and --enable-postproc should be an
optional extra configure rather than a default config option. Thoughts?

Thank you.

Regards,
Punya
