[PATCH] Fix DW_FORM_ref4 values in dw2-op-out-param.S

- Subject: [PATCH] Fix DW_FORM_ref4 values in dw2-op-out-param.S
- Authentication-results: sourceware.org; auth=none
Hi noticed this test was failing and diagnosed it as being
due to bad DW_FORM_ref4 values.
The current values work if one assumes the CU is the first one in
..debug_info. I've got glibc debug info installed which breaks
that assumption.

* gdb.dwarf2/dw2-op-out-param.S: Make DW_FORM_ref4 values be the offset
from the start of the CU.
