gcc44: Instruct linkers to create GNU hash tables

The real-time linker has just been taught how to use GNU hash tables
to speed up symbol lookup.  However, the linkers only generate SysV
hashes by default, so the specs file is being altered to generate
both types of hashes for every shared library and dynamic executable
for a while.  Maybe after a release or two we can consider only
generating the superior GNU hash, which will break forward compatibility
with older releases.

rtld: Support DT_GNU_HASH (startup performance increase)

This is another "First BSD to get" feature that Linux and Solaris
had years ago.  Essentially DT_GNU_HASH is a GNU extension to the ELF
format that allows symbol searches much faster than the System V ABI
standard hash does.  Both versions of our binutils have the capability
of generating GNU hashes alongside of (or instead of) the SysV hash.

The benefit comes at the real-time link stage when the rtld is
searching the libraries for symbols.  For very large programs
written in languages such as c++ that tend to link in many libraries
with many symbols, the reduction in start-time can be dramatic.

According to benchmarks done by binutils team in 2006, more than 90% of
the symbol queries of OpenOffice Writer are rejected by the Bloom filter
before the string comparison takes place:

- Register ifaddr_event handler for gratuituous ARP; it won't

  parent.  The event handler is registered as the last

kern build: Tweak ldscripts for gold linker

The gold linker v2.21 was able to link a working kernel although its

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
