elf2flt & default entry 000080d0

uClinux already has default compile flag -elf2flt
ld relink user init program to 000080d0 during compile, need to verify if this is correct setting.
Once this is corrected, there may be no memory address loading issue.
FLT user program has distinct file header from of
text/data/bss for program loader

we may need addition program elf2flt.ld to score_tool toolchain.
