Potential new signing strategies ( for example signing grub, fwupdate and
vmlinuz with separate certificates ) require shim to support a vendor
provided bundle of trusted certificates and hashes, which allows shim to
"whitelist" EFI binaries matching either certificate by signature, or hash
in the vendor_db.. Functionality is similar to vendor_dbx ( vendor blacklist
). Patch is a polished version of code, authored by P. Jones.

objcopy only knows about -D for some targets.
ld only believes in --no-insert-timestamp in some versions.
dd takes off and nukes the site from orbit.
It's the only way to be sure.

I don't think the x86 binaries clang builds will actually work unless
they just infer -maccumulate-outgoing-args from __attribute__((__ms_abi__),
but it's nice to have the analyzer working.
