I don't think I link main twice, here is my Makefile:

# Automatic generation of dependencies
#
# This magic code fragment from GNU make manual uses the SDCC compiler -M option
# to create a Makefile fragment for each C-source file describing the
dependencies.
#
# Traditionally these fragments have the type '.d' but SDCC seems to delete them
# when it compiles files, so I use '.dep' here.
#
# Also SDCC '-M' option produces wrong dependency for the file being compiled
# in the sense that it does not contain the path, only the filename. Hence
# the 'sed' command has been mangled to inject the missing path to the fragment.
#
# First include the dependencies
include $(addprefix $(OBJDIR)/, $(SRCS:.c=.dep))
# Then recreate them
$(OBJDIR)/%.dep: %.c $$(@D)/.f
