150f500426 arch: allow adding a suffix to the arch-part of a tuple
For some architectures, it is legit to have an alternate value in the
'architecture' part of the tuple. For example:
    armv5te-*
    armv7a8-*

Besides, some packages expect the tuple to reflect the arch variant
(eg. openMPI) to detect the variant's capabilities (eg. atomic
primitives).

This patch adds an option for the user to specify a suffix to be added
to the arch-part of the tuple.

5ddbc863e1 scripts/functions: fix endless loop in debug-shell with IO redirection
CT_DEBUG_INTERACTIVE is disabled when stdin, stdout or
stderr are redirected, but the check is only done at
the start of the build and doesn't catch when individual
build commands use redirection.  When stdin is redirected
it will cause the debug shell to exit immediately, causing
and endless loop.  Thus, save the stdin/our/err file handles
and restore them before invoking the debug shell.

f378c3c1ff scripts/functions: return a proper error code in CT_DoExecLog
Since we added the debug-shell feature, CT_DoExecLog no longer

This breaks the download mechanism, which relies on CT_DoExecLog

at the specified URL.

dd98145bc1 scripts: add option to start an interactive debug shell
Add an option that, when a command fails:
  - starts an interactive shell with the failed command's environment
  - attempts re-execution of the failed command, continues, or aborts

Before starting the debug-shell, the backtrace is printed.
When exiting for an abort, the standard error message is printed.

964f379a42 scripts: fix dumping execution backtrace
Dumping the backtrace has been broken since changeset #652e56d6d35a:
    scripts: execute each steps in a subshell

We can spawn sub-sub-shells in some cases.

The way the fault handler works is to dump the backtrace, but to avoid
printing it once for every sub-shell (which could get quite confusing),
it simply exits when it detects that it is being run in a sub-shell,
leaving to the top-level shell the work to dump the backtrace.

Because each step is executed in its own sub-shell, the variable arrays
that contain the step name, the source file and line number, are lost
when exiting the per-step sub-shell.

Hence, the backtrace is currently limited to printing only the top-level
main procedure of the shell.

Fix this thus:
- when dumping the bckatraces for the steps & the functions, remember
  it was dumped, and only dump it if it was not already dumped
- at the top-level shell, print the hints

Also, rename the top-level step label.

Some packages are available as LZMA tarballs. LZMA is a relatively recent

faster decompression. LZMA is now deprecated in favor of XZ, but some
packages switched to LZMA when XZ was not yet available, or still in its
infancy. Latest XZ (which totaly obsoletes LZMA) offers a backward LZMA-
compatible utility, so we can check for 'lzma' nonetheless.

bdf0b26e19 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.

98ceb8faf3 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
------------------------------------------------------------

5e27ad1e5a 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.

807daf12d0 scripts: allow logging of commands with variables
In a lot of places, we need to call some commands with specific
variable settings, a-la:
  var1=val1 var2=val2 /foo/bar/buz opt1 opt2

Unfortunately, we currently can not log the variable settings.

Enhance CT_DoExecLog with a crude heuristic that works pretty well
and that can also log setting variables.

7bfa4139ad scripts: leave changelog in build dir, copy to install dir
Users tend to look for the build log in the current working directory,
rather than in the toolchain's installation dir. While bundling the build
log in the toolchain installation dir is nice for distribution and review,
it can be easier to have the build log readily available in the working
directory, as it is quicker to get to it.

So, the build log stays in the working directory until the toolchain is
completely and successfully built, and then a (compressed) copy is made.
