i'm no expert on the sdcc toolchain, but in our case, we don't invoke
sdld directly. we simply invoke sdcc as the linker. the man page and
usage message for sdcc both include linker options.
we don't use all the keil options you do, so it might not be helpful,
but the two Makefile.{sdcc,keil} makefiles here build the same body of
code with the respective toolchains:
