Subject: [PATCH 1/2] parisc: vdso: remove dead code in vdso32/Makefile

This commit removes the unused build rule because 'obj-cvdso32' is
not defined.

If you add a C file into arch/parisc/kernel/vdso32/ in the future,
you can revert this change. The kernel does not keep code that
may or may not be used.
