Subject: ARM: 8385/1: VDSO: group link options
From: Nathan Lynch <nathan_lynch@xxxxxxxxxx>
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.
