Add a toolchain-wide option to enable multilib.
This is currently a noop, and will be implemented
in subsequent patches for each impacted components.

In some cases, it might be desirable to use the system zlib
Eg. because latest gcc seem to be totally borked when it comes
to multilib, and tries to build a multilib host zlib, when it
is *absolutely* *not* needed: we want mulitlib on the target,
not on the host! Sigh... :-(

Do not prompt for the type of floating-point support, if the
architecture did not explicitly stated that it did support it.

Changeset #149c33923f47 broke the architectures that do not
support the --with-float=X ./configure flag (in gcc). For example,
x86_64 does not support it.
Add a new blind config option that architectures can set to tell
they support floating point selection.

First, 'SUPPORT' should be spelled 'SUPPORTS'.
Second, 'SUPPORT_XXX' really means 'supports --with-xxx', so rename the
affected options accordingly. Update the affected archs to match the new
namings.

Add support for building the HTML and PDF manuals for the major
components. Implement for binutils, GCC, GDB, and GLIBC.
Always build all manuals and install a subset. Be explicit about the
subset to reduce the clutter and to avoid getting copies of common
manuals like bfd from all of the sourceware based components. Downside of
being explicit is that you need to update it when a new component
comes along.
Build the manuals as part of the last GCC build, namely 'cc' for glibc
based ones and cc_core_pass_2 for baremetal.
An example of the output is at:

ARM compilers can be built for soft float (software only, floats in
core registers), hard float (uses floating point instructions, floats
in FPU registers), or the half-way house softfp (uses floating point
instructions, floats in core registers).

Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.
For example, ARM supports this mode (to come in the next changeset).
Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.

Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.
So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

Allow the user to configure extra flags to pass to the host compiler

Useful on Ubuntu to turn off the stack protector and fortify defaults
so the program stands a better chance of running on other distros.
