Can you please try the following?
echo > Makefile <<\EOF
LN_S=cp -p
ifeq (cp -p,$(LN_S))
LN_S_RECURSIVE=cp -pr
else
LN_S_RECURSIVE=$(LN_S)
endif
all:
echo $(LN_S_RECURSIVE)
EOF
make; make LN_S='ln -s'; make LN_S='cp -p'
sed 's/LN_S=cp -p/LN_S=ln -s/' Makefile
make; make LN_S='ln -s'; make LN_S='cp -p'
Works for me just fine. Perhaps you have buggy make?
