4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Slaby <jslaby@xxxxxxx>
commit 755396163148b50fe1afb4bdd3365e47f3ff7a42 upstream.
Commit 7ed1c1901fe5 (tools: fix cross-compile var clobbering) removed
setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
(acpidump) in power/acpi:
ld: unrecognized option '-D_LINUX'
The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
particular change and let LD be $(CC) again. Note that the old behaviour
was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
the commit 7ed1c1901fe5. We use $(CC) for that reason.
