[PATCH 3/3] gdb: make target_auxv_parse static and rename

[Simon Marchi <simon.marchi@polymtl.ca>]

It is only used in auxv.c.  Also, given it is not strictly a wrapper
around target_ops::auxv (since 27a48a9223d0 "Add auxv parsing to the
architecture vector."), I think that the name prefixed with target is a
bit misleading.  Rename to just parse_auxv.
