Paul Smith 4f1933620f kbuild: change kbuild to not rely on incorrect GNU make behavior 
The kbuild system takes advantage of an incorrect behavior in GNU make.
Once this behavior is fixed, all files in the kernel rebuild every time,
even if nothing has changed.  This patch ensures kbuild works with both
the incorrect and correct behaviors of GNU make.

For more details on the incorrect behavior, see:

http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html

Changes in this patch:
  - Keep all targets that are to be marked .PHONY in a variable, PHONY.
  - Add .PHONY: $(PHONY) to mark them properly.
  - Remove any $(PHONY) files from the $? list when determining whether
    targets are up-to-date or not.

Makefile to build lxdialog package

check-lxdialog := $(srctree)/$(src)/check-lxdialog.sh

Use reursively expanded variables so we do not call gcc unless

we really need to do so. (Do not call gcc as part of make mrproper)

HOST_EXTRACFLAGS = $(shell $(CONFIG_SHELL) $(check-lxdialog) -ccflags) HOST_LOADLIBES = $(shell $(CONFIG_SHELL) $(check-lxdialog) -ldflags $(HOSTCC))

HOST_EXTRACFLAGS += -DLOCALE

PHONY += dochecklxdialog $(obj)/dochecklxdialog: $(Q)$(CONFIG_SHELL) $(check-lxdialog) -check $(HOSTCC) $(HOST_LOADLIBES)

hostprogs-y := lxdialog always := $(hostprogs-y) dochecklxdialog

lxdialog-objs := checklist.o menubox.o textbox.o yesno.o inputbox.o
