What does "./configure --enable-botstrap; make bootstrap" do?
The same as plain make. bootstrap is the default target when
--enable-bootstrap is given, and its behavior resembles a "bubblestrap"
(see later) in the old system.
This removes the wart where "make" following a "make bootstrap" invoked
a "quickstrap" and often caused comparison failures. To the next topic...
It would help also if you add to the wiki explanation of what exactly all
these options do. Especially bubblestrap vs quickstrap vs restrap.
... bubblestrap rebuilds only changed files. quickstrap rebuilds only
the last stage. restrap takes (took?) a non-bootstrap build, uses it as
stage1, and then completes the bootstrap.
