Revert "fail on changed init section"

This reverts commit 7b15e23149bcb9e8b4e671542485ac8d5d54ec1b.

After reverting this commit, create-diff-object correctly detects,
during the inclusion check, that the .init* section hasn't been
included and fails, as it should.  Not sure that this was ever
a problem, but the fix is not needed.

Fixes #103
