[ Upstream commit ff6d27823f619892ab96f7461764840e0d786b15 ]

The 32-bit vDSO is not needed and not normally built for 64-bit
little-endian configurations.  However, the vdso_install target still
builds and installs it.  Add the same config condition as is normally
used for the build.

Fixes: e0d005916994 ("powerpc/vdso: Disable building the 32-bit VDSO ...")
