Summary

vdso_wrap.S embeds the linked vdso with .incbin. ccache hashes the
wrapper source and command line but not the embedded image, so a
WITH_CCACHE_BUILD rebuild can reuse a wrapper object embedding a stale
vdso. Disable ccache for this compile; it is a trivial .incbin, so
nothing worth caching is lost.
