Upstream a local patch from rawhide

Currently, we carry this fix downstream:

Fix abidw output for missing variadic arguments

GCC forgets to add the varidic arguments into debugging data if the
compilation unit is built with -flto option. As a result, the prebuilt
XML ABI dumps were missing the last argument at 4 functions (e.g.
efi_error_set()).

This was unnoticed until Fedora enabled LTO globally and had to
disable LTO in efivar explicitly because efivar uses symbol versioning
with top-level assembler statements which is not compatible with LTO.

Since then the abicheck failed:

This patch corrects the pregenerated abixml files that were probably
generated with the faulty GCC.

I've pulled this, not so much because it's necessarily useful as is - when we regenerate for the newest ABI it'll inevitably be wrong again unless gcc is fixed - but so we can find it easily for reference later.
