kern build: Tweak ldscripts for gold linker

The gold linker v2.21 was able to link a working kernel although its
modules were unloadable.  The gold linker v2.22 could build loadable
modules, but the kernel wouldn't boot!  It's not clear why the modules
started to work -- my guess is that the ancient ldscripts used during
the 2.21 trial were the culprit.

The gold linker changed its ELF program header handling defaults for
version 2.22, and this resulted in an extra LOAD segment reserved only
for the program headers.  The DragonFly loader wasn't expecting that
and instantly rebooted when trying to load a gold kernel.

The solution was to add a PHDRS section to the ldscripts to specify
exactly the section to segment mapping, and prevent gold from putting
the elf headers in their own load segment.  Now gold matches gnu ld
linker in having only two LOAD segments, text and data.

As a curiousity, gold sets the LOAD segment alignment value at 0x1000
for both i386 and x86_64, where gnu ld sets the segment alignment at
0x1000 for i386 and 0x200000 for x86_64.  This seems to have no impact
on the loading of the kernel.

rtld: Add support for preinit, init, and fini arrays

As far as I can tell, all BSDs limit their ELF executable file
initialization and termination to the .init and .fini sections.  In
contrast, Linux has additionally supported the .preinit_array,
.init_array, and .fini_array sections for over a decade through glibc.
With this commit, DragonFly becomes the first BSD to support these
arrays of function pointers.  It was tested using test cases taken from
glibc, gnu ld linker, and the gold linker.

For the main executable file, the .init_array and .fini_array sections
are handled by crt1, just like .init and .fini are.  In the case of
a statically linked binary, the .preinit_array section is also handled
by crt1.  The real-time linker handles the .init_array and .fini_array
sections for dynamically shared objects (libraries) and .preinit_array
for dynamically-linked binaries.  There are no .preinit_array sections
in the DSOs per standard.

These sections are described by the System V Application Binary Interface
http://www.sco.com/developers/gabi/latest/ch4.sheader.html#special_sections

The .init_array and .fini_array handling by rtld was reviewed by
