[PATCH] powerpc: vdso: Make vdso32 installation conditional in vdso_install

[Ben Hutchings]

[-- Attachment #1: Type: text/plain, Size: 831 bytes --]

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.
