[rfa] symfile.c - fix apparently uninitialized my_cleanups

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

I think the attatched is correct.  ``my_cleanups'' was always
initialized but in a somewhat obscure way.  It probably illustrates a
better way of doing cleanups for a function - unconditionally setup the
cleanup at the very start.

Ok?
