g77 testsuite failures under hpux 10.20

[John David Anglin]

With the CVS source from a couple of days ago, various failures occur
in the g77 testsuite.  All the failures are similar:

Running /xxx/gnu/gcc-2.96/gcc/testsuite/g77.f-torture/compile/compile.exp ...

compiler exited with status 1

This is the assembly code around line 179:

        ldo RR'__g77_cilist_1___3-$global$(%r19),%r26
	.CALL ARGW0=GR
	bl ,%r2
	nop

Somehow in these lines, the function to be called has disappeared.  This
happens in some but not all function calls.
