image_copy_start/end are defined as c variables in order to force the
compiler emit relative references. However, defining those within a section
definition will do the same thing since [0].
So let's remove the special sections from the linker scripts, the
variable definitions from sections.c and define them as a symbols within
a section.
[0] binutils commit 6b3b0ab89663 ("Make linker assigned symbol dynamic only for
shared object")
