397358d9ac Disable sbrk() use in GNU tools.
We're studing the possibility of deprecating sbrk().  To make it easier
we're removing unnecessicary uses in the base system.  None of these
tools require sbrk(), but they agressively prefer it for no good reason.

bafc378147 Update libstdc++ configuration.
Its been quite a while since the last time we updated this and since then
we have grown iconv and a bunch of complex math functions.

This only applies to the platforms which still use GCC 4.2.1 in the
toolchain.

104f6a2dcd Fix GCC 4.2.1 to honor --sysroot for includes.
- Change the C++ directory entries to honor --sysroot if it is set.
- Don't define CROSS_INCLUDE_DIR for the cross compiler.  Instead, set
  TARGET_SYSTEM_ROOT to point to WORLDTMP and always define
  STANDARD_INCLUDE_DIR.
- Change STANDARD_INCLUDE_DIR and the C++ include directories to just
  start with "/usr" always.  The compiler will prepend the sysroot when
  doing cross-builds.  GCC_INCLUDE_DIR (which contains headers that ship
  with the compiler such as intrinsincs rather than OS-supplied headers)
  remains hardcoded to look in TOOLS_PREFIX.

LLD_BOOTSTRAP (build) is independent of LLD_IS_LD (installed) so they

d86c1f0dc1 i386 4/4G split.
The change makes the user and kernel address spaces on i386
independent, giving each almost the full 4G of usable virtual addresses
except for one PDE at top used for trampoline and per-CPU trampoline
stacks, and system structures that must be always mapped, namely IDT,
GDT, common TSS and LDT, and process-private TSS and LDT if allocated.

By using 1:1 mapping for the kernel text and data, it appeared
possible to eliminate assembler part of the locore.S which bootstraps
initial page table and KPTmap.  The code is rewritten in C and moved
into the pmap_cold(). The comment in vmparam.h explains the KVA
layout.

There is no PCID mechanism available in protected mode, so each
kernel/user switch forth and back completely flushes the TLB, except
for the trampoline PTD region. The TLB invalidations for userspace
becomes trivial, because IPI handlers switch page tables. On the other
hand, context switches no longer need to reload %cr3.

copyout(9) was rewritten to use vm_fault_quick_hold().  An issue for
new copyout(9) is compatibility with wiring user buffers around sysctl
handlers. This explains two kind of locks for copyout ptes and
accounting of the vslock() calls.  The vm_fault_quick_hold() AKA slow
path, is only tried after the 'fast path' failed, which temporary
changes mapping to the userspace and copies the data to/from small
per-cpu buffer in the trampoline.  If a page fault occurs during the
copy, it is short-circuit by exception.s to not even reach C code.

The change was motivated by the need to implement the Meltdown
mitigation, but instead of KPTI the full split is done.  The i386
architecture already shows the sizing problems, in particular, it is
impossible to link clang and lld with debugging.  I expect that the
issues due to the virtual address space limits would only exaggerate
and the split gives more liveness to the platform.

Make armv7 as a new MACHINE_ARCH.

Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.

Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).
