[PATCH] ppc64: revert implement-a-vdso-and-use-it-for-signal-trampoline-gas-workaround

We don't actually need this.

The reason why the ppc64 build exploded was that I had CC="gcc -m64", and even
though the build system turns that into "gcc -m64 -m32", that is,
surprisingly, equivalent to "gcc -m64".
