Then two tests rely on .interp being the first section.
llvm-bolt would crash if lld places .interp after .got
(f639b57f7993cadb82ee9c36f04703ae4430ed85).
For best portability, when a linker scripts specifies a SECTIONS
command, the first section for each PT_LOAD segment should be specified
with a MAXPAGESIZE alignment. Otherwise, linkers have freedom to decide
how to place orphan sections, which might break intention.
We need to search referenced section based on relocations symbol section
to properly match end section symbols. For example on some binaries we
can observe that init_array_end/fini_array_end might be "placed" in to
the gap and since no section could be found for address the relocation
would be skipped resulting in wrong ADRP imm after emitting new text
resulting in binary sigsegv.
Credits for the test to Vladislav Khmelevskii aka yota9.
