rework 39096c4e04286d1dd23c2808a3a0ec4b9c89e709

This change should have the same effect while making
BASHRC_CONTENT() constant(ish) again. At least it does
not break if the bash srcipt content start to use more
"printf %s" command.
init-in-bash brokes due to recent changes on BASHRC_CONTENT() function.

in that case, the whol build process will fail, and we can
just need to source a working version of bashrc somewhere.
