[PATCH] powerpc/vdso: Add support for unstripped vDSO installation

[Thomas Weißschuh]

'make vdso_install' can install the unstripped vDSO files,
so that they can be shipped to the target system for debugging purposes.

Add the necessary variables so this also works on PowerPC.

Adding a build ID to the vdso with --build-id=sha1 would also make
debugging easier.
And then add powerpc to scripts/Makefile.vdsoinst, or wait for [0].
