[Xen-devel] [PATCH] x86: fix efi.lds dependency generation

[Wei Liu <wei.liu2@xxxxxxxxxx>]

RANDCONFIG builds discover efi.lds is not updated when autogenerated
headers are updated.

Upon inspection, the generated .d file contains xen.lds.o as target,
not the once thought efi.lds.o. That's because gcc disregards the
output object name specified by -o when generating dependency, so the
sed invocation has no effect.

Fix the sed rune.
