Problems with tcb-offsets.h

[Martin Schwidefsky]

Hi,
cvs head of today doesn't compile on s390-32 and probably other
architectures as well because tcb-offsets.h doesn't get generated from
tcb-offsets.sym. The reason seems to be one of the latest changes
in Makerules:

+# Avoid the .h.d files for any .sym files whose .h files don't exist yet.

++gen-as-const := $(gen-as-const-headers:%.sym=$(common-objpfx)%.h)
++depfiles += $(addsuffix .d,$(filter $(wildcard $(+gen-as-const)),\
+						$(+gen-as-const)))
 
 ifdef +depfiles
 ifneq ($(no_deps),t)

Without this it compiles fine. Any ideas ?
