[Buildroot] xtensa buildroot: how to enable xtensa-linux-gcc with --mno-flix ??

[hitheshm at tataelxsi.co.in]

Hi,
I am using xtensa buildroot (xtensa_snapshot.tar.gz (Sources) ) downloaded
from http://www.linux-xtensa.org/download.html 
to cross compilation linux-xtensa for xtensa platforms.But now I want to use
"-mno-flix" option with xtensa-linux-gcc 
currently it is not enabled.I have tried to configure the same with "make
uclibc-menuconfig" and "make menuconfig" as explained on
the www.linux-xtensa.org.  But I couldn't find out the "-mno-flix".If is it
possible please help to configure buildroot to enable "-mno-flix" option.
 
Please help me out..
 
Thanks in advance..
 
Thanks,
--Hitesh
