Using your kbuild.git, these blow up for me:
LD .tmp_vmlinux1
sh4-linux-ld:arch/sh/kernel/vmlinux.lds:364: ignoring invalid character `#' in
script
sh4-linux-ld:arch/sh/kernel/vmlinux.lds:364: ignoring invalid character `#' in

...
This comes out as:
.text : {
*(.text.head)
. = ALIGN(8);
*(.text)
*(.text.init.refok)
*(.exit.text.refok)
*(.dev##init.text)
*(.dev##exit.text)
. = ALIGN(8);
__sched_text_start = .; *(.sched.text)
__sched_text_end = .;
. = ALIGN(8);
__lock_text_start = .; *(.spinlock.text)
__lock_text_end = .;
. = ALIGN(8);
__kprobes_text_start = .; *(.kprobes.text)
__kprobes_text_end = .;
*(.fixup)
*(.gnu.warning)
...
so the ## is being taken directly rather than acting as a concatenation.
