Not sure I understand what this patch fixes that the Vulkan spec does
not have a recommendation or two for. Can anyone elaborate step by
step what we're having here, please ?
Furthermore this sounds like a developer only thing, so perhaps we
should restrict it there ? As-is we're effectively annoying some/most
distros.

IIRC '< $<' was only applicable in some cases according to POSIX make.
One the relative/full path, I think that non-gnumake implementations
were having issues with the proposed solution. If anyone can confirm
that it works I'm ok with changing it.
