45eff3df96 remove CONSTRUCTORS from kernel linker scripts
The linker script CONSTRUCTORS keyword is only meaningful "when linking
object file formats which do not support arbitrary sections, such as
ECOFF and XCOFF"[1] and is ignored for other object file formats.

LLVM's lld does not yet accept (and ignore) CONSTRUCTORS, so just remove
CONSTRUCTORS from the linker scripts as it has no effect.

466d476aac Fix build with new binutils. This gets a working kernel with GCC 5.2 and
binutils 2.24. Without this, the self-relocation code in locore64.S was
failing due to a misaligned TOC section.

66c8095956 Rename elf*-powerpc into elf*-powerpc-freebsd in binutils
The powerpc support was the only supported architecture not prepending the elf format name
with "-freebsd" in base this change makes it consistent with other architectures.
On newer version of binutils the powerpc format is also prepended with "-freebsd".

Also modify the kernel ldscripts in that regards.

As a result it is now possible cross build the kernel on powerpc using newer binutils

618abe8ba1 Add the .opd section, this is helps booting a profiled kernel.
Adjust the OUTPUT_ARCH and use the builtin ALIGN() to adjust the data segment.

6ba63f2d8c In fact, we don't need any of these __DYNAMIC. it is a.out leftover and commented out. 2011-01-20 19:24:50 +00:00
