The sections (= parts of a segment) inside an object file are already marked
in the header of the object file with the required alignment. Since the linker
cannot add bytes within a section (this would change the size of the data and
would therefore interfere with address calculations done by the assembler),
an easier solution would be to pad the start of the section to the required
