Log: For riscv kernel builds, add -N to LDFLAGS instead of replacing the SYSTEM_LD variable. This avoids duplicating the contents of SYSTEM_LD from kern.pre.mk just to add the -N flag to it. If the basic linker command ever needs to be changed, this will be one less place that has to be found and fixed. Some testing by kp@ indicates that the -N flag may not be needed at all, so a comment to that effect is also added, and the -N flag may be removed in a followup commit.
