how to delete symbol link created at compile time

[She, Kerry]

Hello,

Some mainboard support more than one family of CPUs with same socket
type,

Such as SuperMicro/h8scm:

http://www.supermicro.com/Aplus/motherboard/Opteron4100/SR56x0/H8SCM-F.c
fm

My implementation is the mainboard CPU type can be configured as
family10 or family15 CPU.

In order to eliminate the duplicated code, both configuration shares
most of the platform code,

but some code can't be shared between different family of CPUs.

Take devicetree.cb as an example,

I have created 2 devicetree file :

devicetree_f15.cb for platform with family 15 CPU

devicetree_f10.cb  for platform with family 10 CPU

I changed the makefile to create a symbol link "devicetree.cb" link to
devicetree_f10.cb or devicetree_f15.cb at compile time.

The problem is that I can't delete the symbol link when make
clean/distclean.

I found that make clean/distclean will not traverse the src/ directory.

How can I get this symbol link removed when doing a make clean.

Any other suggestion is welcome.

Kerry,

I thought about a recursive call through the subdirs to do a make
clean, but that would make a lot of errors for most Makefiles.inc
because they don't have a clean target. I wonder if there is a better
way.

What are the differences exactly?

If possible, I'd like to look for a solution that allows a single image
to work with both families.

symlinks won't work on Win32 (except in cygwin, which doesn't count).
