I tried modifying the makefile by replacing the link command with this:
main.ihx: $(OBJECTS)
$(CC) $(MFLAGS) $(LFLAGS) $(OBJECTS)
SDCC now complains that it doesn't know what to do with the .o files, which
are all there and properly compiled.
Here is the modified makefile, and a makefile from another project, which
compiles and links properly, with the same version of SDCC and executing from
the same shell (so that the same environment variables are used).
I'm suspecting some black magic here... :)
