[PATCH] libgcc: fix a warning calling find_fde_tail

[Xi Ruoyao via Gcc-patches]

Bootstrapped on x86_64-linux-gnu.  OK for master?

The third parameter of find_fde_tail is an _Unwind_Ptr (which is an
integer type instead of a pointer), but we are passing NULL to it.  This
causes a -Wint-conversion warning.

libgcc/

        * unwind-dw2-fde-dip.c (_Unwind_Find_FDE): Call find_fde_tail
          with 0 instead of NULL.
