WAF build system: configure to prepend .o to all links?

For now I just change the one in the tree but I don't want to do that.  I don't want a BSP variant, either, since it's a custom board that shouldn't have changes in the tree.

I can't over-ride LDFLAGS since that is appended in the command line after the libraries were already added.  So I want to add a .o to the sources or a flag that goes in after the "-o" for the program output.

I checked in a patch which should help to address this problem:

Could you try if this works in config.ini

LINKFLAGS = dts.o

?
