    libelf: Initialize n to zero in elf_getarsym.

    When building with gcc -Os it seems we can inline read_number_entries
    but if that function fails then n will not be initialized. GCC seems not
    to realize that in that case n won't be used at all. Explicitly initialize
    n to zero to prevent a spurious error: 'n' may be used uninitialized in
    this function [-Werror=maybe-uninitialized] in that case.
