I tried the following command and it seems work:
for f in `find * -type f`; do sed -i 's/\<_end\>/__bss_end/g' $f; done
but when I tried to build, I got some error in standalone example:

It looks like that _end as end of BSS section is a convention to GNU toolchain.
Should I simply fix it by hand, or should we reconsider the whole naming thing?
best regards,
