--- Comment #2 from Akhilesh Kumar <akhilesh.k at samsung dot com> ---
Now i configured gcc with --enable-multilib then also unable to build for lp64f

is this because ABI_FLEN is for 32 default lp64d is for 64  ? 

And if i want to compile the same for lp64d, lp64f and lp64 what changes i need
to do during gcc configuration
