internals: fix stripping host binaries

The gcc used by linaro has a version number specific to Linaro, but
identifies itself with its upstream version numbering scheme.

This breaks the strip in the finish step, because the actual gcc version
is not the same as the configured one (eg. 4.5.2 vs. linaro-4.5-2011.02-0).

functions: pretty print error messages

Reformat the error messages:
- strip ${CT_LIB_DIR} from scripts path names
- strip ${CT_TOP_DIR} from build.log path and docs path
- overall shorter lines
- point to the known-issues file

docs: add a status for know issues

As time passes, a known issues can be no longer applicable (because
the component has been fixed, or a workaround ahs been added in the
crosstool-NG scripts/config...).

Some may also be unconfirmed, with no way to easily trigger the error,
or applies to old versions of components...

Add a status for every known issues.

docs: use the error message in the known issues titles

This helps users find the appropriate known issue entry.

functions: fix date calculations

In case date(1) does not support nanosecond resolution, it does
not interpret '%N', and leave it as-is. So we have to remove it.

Note that some versions replaces '%N' with 'N', so we have to
take this into account as well.

functions: avoid CR when progress bar is not enabled

Using CT-NG with progress bar disabled, still prints CR ('\r') characters
on the output. When you capture the output to a file as part of an
automated build, it shows extra empty lines.

For example:

------------------------------------------------------------
[INFO ] Performing some trivial sanity checks

[INFO ] Build started 20110404.113619

[INFO ] Building environment variables

[EXTRA] Preparing working directories

[EXTRA] Installing user-supplied crosstool-NG configuration

complibs: disable building shared libs

Managing the shared version of the companion libraries
has become cumbersome.

Also, it will one day be possible to use the companion
libraries from the host distribution, and then we will
be able to easily use either shared or static libs.

As a side note, while working on the canadian-rework
series, it has become quite more complex to properly
handle shared companion libraries, as they need to be
built both for the build and gost systems. That's not
easy to handle. At all.
