Check for python2/python3 and if found, pass them to --with-python.
Allow user to override the choice via a new config option. This
fixes systems where there is no "python", only "python2" or "python3".

If the build machine lacks tic, we need to build it in the first pass
even if host==build: ncurses Makefiles are not smart enough to build
'tic' first and use the just-built tic to compile fallback terminfo.

On cygwin, creating both "foo.exe" and "foo" results in 'ln -sf'
returning an error ("File exists"). However, ln silently removes
the "foo.exe" in this case, so an attempt to re-run the same command
manually then succeeds.
Hence, make binutils.sh also create symlinks with .exe prefix,
using the new & shiny routine.

- libpthread requires iteration over multilibs, unlike the core, it
does not detect and build multilibs by itself.
- Disable parallel builds for mingw-w64 components; until mingw-w64 core
builds clean, I am not trusting it.
- Make the list of tools to build configurable
- Turn on multilib in x86_64 sample.
- Make warnings about tuple less redundant. As in, "one WARN is enough,
no need to shout it three times".
- Messages about various steps/substeps are more aligned with the rest
of the components.
- Use 'make' instead of ${make} to invoke the companion make just built,
if applicable.

... when determining if it can be linked statically, and if Python
scripting should default to y.
Prompted by a failure of i686-w64-mingw32,nios2-spico-elf sample
on a system where configure didn't report static linking support.

It is only used if this libc flavor uses a multilib iterator (and not
determines the multilibs itself). This class currently includes glibc,
uClibc, musl - but they explicitly select CC_CORE_PASSES_NEEDED anyway.

(see the comments in the code for details on the issue)
Old workaround in 100-gcc.sh stopped working (probably, due to one
of GCC version upgrades), so switch to the other approach originally
described there: adjust the list of multilibs to not include the
default target explicitly.

... enabled by default for multilib and disabled otherwise. Buildroot
has been complaining about /etc/ld.so.conf presence for almost a year
now and I missed that.
After the release, xldd will be modified to query the compiler for
the list of multilibs to search. This would be too invasive change
before 1.23, though.
Note that it may lead to configurations where xldd currently does not
find the libraries (if both DEMULTILIB and CREATE_LDSO_CONF are turned
off). This is not the default setting in Kconfig, though.

It turns out buildroot does not currently accept a toolchain where a dynamic
linker does not reside in the multi-os-directory. Unfortunately this is
how glibc installs itself on AArch64 without any extra tricks.
So, provide an option to force everything into /lib or /usr/lib; patch to
buildroot will be worked on separately.

GCC does not distinguish the resulting binary by the CFLAGS (e.g. based
on which -march= was given). This means, while it will use the right
libraries for linking, at runtime they are all going to request the same
ld.so path and load the libraries from the same default path.

Also a fix for CT_IterateMultilibs: it didn't pass multi_os_dir_gcc, so
it only worked if the caller did *not* declare it as a local variable.
