Sebastian Bøe 4971d2a084 cmake: Fix "make VERBOSE=1"
It is desired behaviour that when 'make VERBOSE=1' is invoked, the
underlying scripts will be invoked in 'verbose mode', e.g. they have
the flag --verbose passed to them.

This patch modifies all the underlying scripts in the build system to
inject --verbose into the command line when the environment variable
VERBOSE is set.

The environment variable VERBOSE is a CMake concept. CMake will
generate Makefile's that read this environment variable and try to
behave accordingly. Unfortunately, the generated ninja build systems
behave differently and will have to be invoked like this:

VERBOSE=1 ninja -v

This fixes #4851

The 'dpl' argument was unused, causing problems if the privilege
level was not 0.

Andrew Boie bc666ae7f7 x86: implement improved double-fault handler
We now create a special IA hardware task for handling
double faults. This has a known good stack so that if
the kernel tries to push stack data onto an unmapped page,
we don't triple-fault and reset the system.

Andrew Boie 08c291306e x86: generate RAM-based GDT dynamically
We will need this for stack memory protection scenarios
where a writable GDT with Task State Segment descriptors
will be used. The addresses of the TSS segments cannot be
put in the GDT via preprocessor magic due to architecture
requirments that the address be split up into different
fields in the segment descriptor.
