    libgcc: Fix eh_frame fast path in find_fde_tail

    The eh_frame value is only used by linear_search_fdes, not the binary
    search directly in find_fde_tail, so the bug is not immediately
    apparent with most programs.

    Fixes commit e724b0480bfa5ec04f39be8c7290330b495c59de ("libgcc:
    Special-case BFD ld unwind table encodings in find_fde_tail").

    libgcc/

            PR libgcc/109712
            * unwind-dw2-fde-dip.c (find_fde_tail): Correct fast path for
            parsing eh_frame.

    (cherry picked from commit 49310a993308492348119f4033e4db0bda4fe46a)=
