Subject: powerpc: vdso: Make vdso32 installation conditional in vdso_install
Bug-Debian: https://bugs.debian.org/785065
Forwarded: https://lore.kernel.org/linuxppc-dev/20190322042436.nttfgsdpdshco27y@decadent.org.uk/

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 ...")
