I do a "git clean -dfx" when switching branches, but I admit a clean build 
can be slow.

Perhaps we should ask the gnulib maintainers to change bootstrap so that 
it runs gnulib_mk_hook on a temporary file before the comparison and then 
moves the result into place if it's different.  I suppose the reason not 
to move it into place unconditionally is to avoid changing the time stamp.
