Depending on the preceding *(.rodata*) sections, the contents of the
RO_DATA_SECTION macro may be unaligned.
In my case, the initcall table was unaligned, because the preceding
.rodata ended with the defaultenv when CONFIG_KALLSYMS was set to N.
0x00000000000b0a00 0x1c2 arch/arm/lib32/built-in.o
.rodata.unwind_get_byte.str1.1
0x00000000000b0bc2 0x1e arch/arm/lib32/built-in.o
.rodata.default_environment
0x00000000000b0be0 0x1d defaultenv/built-in.o
.rodata.defaultenv_add_base.part.0.str1.1
0x00000000000b0bfd 0x35 defaultenv/built-in.o
.rodata.defaultenv_load.str1.1
0x00000000000b0c32 0x2b defaultenv/built-in.o
0x36 (size before relaxing)
0x00000000000b0c5d <--- oops
__barebox_initcalls_start = .
*(.initcall.0)
Tested on i.MX6 (ARM v7).
