Subject: ARM: 8385/1: VDSO: group link options

From: Nathan Lynch <nathan_lynch@mentor.com>

commit d33ce23b2160d26b27a47092da5d556b5b11a12a upstream.

Currently the VDSO's link options are kind of a mess spread between

ccflags-y and cmd_vdsold.  Collect linker directives into one
variable, VDSO_LDFLAGS, and use that in cmd_vdsold.
