[PATCH] build: make clean removes .*.d and *.d

[pablo@netfilter.org]

From: Pablo Neira Ayuso <pablo@netfilter.org>

While changing from master to nf-nat branch, I hit this error:

make[2]: ***   CC       libipt_CLUSTERIP.oo
No hay ninguna regla para construir el objetivo `../include/net/netfilter/nf_nat.h', necesario para `libipt_DNAT.oo'.  Alto.

by removing *.d and .*.d I get it fixed. Add this to `make clean'
so I can avoid doing this by hand.
