bug in eliminate_regs

[Ulrich Drepper]

The function eliminate_regs in reload1.c is sometimes called without
reload been running.  The call in my case happens to come from
dbxout.c:1936.  But this leaves the variable `reg_eliminate'
uninitialized.

After adding the following patch things are fine again.
