SubjectRE: cris: build creates links in the source directory

That is correct and we have thoughts about using Makfiles and compiler flags
to resolve this instead as done for other architectures.

Subject: cris: build creates links in the source directory

Especially when building with a separate object directory the following
part of arch/cris/Makefile is not so nice since it creates links in the
source directory:

<-- snip -->

# Create some links to make all tools happy
$(SRC_ARCH)/.links:
@rm -rf $(SRC_ARCH)/drivers
@ln -sfn $(SARCH)/drivers $(SRC_ARCH)/drivers
@rm -rf $(SRC_ARCH)/boot
@ln -sfn $(SARCH)/boot $(SRC_ARCH)/boot
@rm -rf $(SRC_ARCH)/lib
@ln -sfn $(SARCH)/lib $(SRC_ARCH)/lib
@rm -f $(SRC_ARCH)/arch/mach
@rm -rf $(SRC_ARCH)/arch
@ln -sfn $(SARCH) $(SRC_ARCH)/arch
ifdef CONFIG_ETRAX_ARCH_V32
@ln -sfn ../$(SARCH)/$(MACH) $(SRC_ARCH)/arch/mach
endif
@rm -rf $(SRC_ARCH)/kernel/vmlinux.lds.S
@ln -sfn ../$(SARCH)/vmlinux.lds.S $(SRC_ARCH)/kernel/vmlinux.lds.S
@rm -rf $(SRC_ARCH)/kernel/asm-offsets.c
@ln -sfn ../$(SARCH)/kernel/asm-offsets.c
$(SRC_ARCH)/kernel/asm-offsets.c
@touch $@

# Create link to sub arch includes
$(srctree)/include/asm-$(ARCH)/.arch: $(wildcard
include/config/arch/*.h)
@echo ' SYMLINK include/asm-$(ARCH)/arch ->
include/asm-$(ARCH)/$(SARCH)'
@rm -f $(srctree)/include/asm-$(ARCH)/arch/mach
@rm -f $(srctree)/include/asm-$(ARCH)/arch
@ln -sf $(SARCH) $(srctree)/include/asm-$(ARCH)/arch
ifdef CONFIG_ETRAX_ARCH_V32
@ln -sf $(MACH) $(srctree)/include/asm-$(ARCH)/arch/mach
endif
@touch $@
<-- snip -->

"Is there not promise of rain?" Ling Tan asked suddenly out
of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.
