ARM: 8321/1: asm-generic: introduce .text.fixup input section
This introduces a new .text.fixup input section that gets emitted
together with the .text section for each input object file.
Note that
*(.text)
*(.text.fixup)
is not the same as
*(.text .text.fixup)
and we are looking for the latter, to ensure that fixup snippets that
are assembled into a separate section in the object file do not end
up out of range for the relative branch instructions it contains if
the .text section itself grows very large.
This helps prevent linker failures on large ARM kernels.
