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:

In the early days, cloog-ppl was bizarrely packaged: the first tarball
did not contain the version in the name of the extracted directory, so
we had to play tricks.
Nowadays, however, the first component of the path are stripped when
extracting a tarball, which means that the created directory will
always be properly named. So, our old tricks do no longer work, and
worse, they break the build.

In the very beginnings, eons ago, autotools also got confused by this
whole build vs. host vs. target, and got it wrong. Now they fixed it,
but they want to keep backward compatibility, so the --target is still
recongised, although ./configure will complain if you do so. It is
better to use --host.

ncurses 5.9 wants tic to be either one of:
- $TIC_PATH
- /usr/bin/tic
Of course, se do not want the latter, for it can be incompatible if the
ncurses in the build system is too old (eg. RHEL 5.6, Debian Lenny...).
So, force TIC_PATH to the location of our own tic.
Also, install tic alongside the other build tools, not in a sub-dir
of the toolchain installation dir.

Some projects are using (or planning to use) crosstool-NG, and are storing
it in their VCS, which might not be Mercurial. At the same time, those
projects may want to track development snapshots versions the way we do
with the Hg identity string (hg id).
Provide a way for these project to do so, without having to patch
./configure, and maintain that patch over-and-over again.

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.
