[Pkg-libvirt-maintainers] Bug#1024504: libvirt FTCBFS: misdetects linux/kvm.h

[Helmut Grohne]

Version: 8.9.0-1

libvirt fails to cross build from source when building on amd64 for
armhf or armel. It uses meson's has_header to figure out whether
linux/kvm.h exists and due to linux-libc-dev:amd64 being installed,
/usr/include/linux/kvm.h exists. has_header is able to figure this out
without actually including it. When libvirt actually #includes it,
asm/kvm.h is missing as that's a multiarch headers. Thus linux headers
should be tested with check_header, which actually #includes it. While
has_header may seem relatively useless at this point, it is far quicker
than check_header. Thus I'm proposing to only employ check_header for
linux headers. I'm attaching a patch for your convenience.
