The generated sysnum.h is different for o32/n32/64 ABIs.
This needs to be revisited; either do this for all architecutres or
perhaps, compare the headers for various multilibs and combine them
if the are identical.

GCC7 also checks -fsanitize=divide-by-zero, which generates a trap
and in sh4, traps in rtld result in link failure. Pull the fix from
upstream, although it is not a complete fix, I think: this still
generates a trap (SIGILL) rather than the intended SIGFPE.

... it is possible to just not set it in the configuration, why force
it? It just increases the complexity in Kconfig.

Instead, prepare the files as a part of bootstrap and install them.
This avoids rebuilding these files in each working directory; they
don't change anyway as they are generated from the same installed
source.

from configure rather than substitute it from Makefile. Eventually we
might want to get rid of configure.in completely, doing on-the-fly
checks at the time of `ct-ng build`, but that is left for another day.

- Existing 110-fix-eabihf.patch did not apply to 1.20.0 and earlier
- This patch is also applicable to 2.x versions
- The patch needs to be applied to both configure.in/configure
- Existing 200-optimising-for-space.patch also applies to all versions
before 2.4.0
- Similar issues exist in other config/mt-* files
- m68k patch is applicable to 2.* versions

Building with CT_MINGW_TOOLS unset before this change produces:
/usr/local/ct-ng/lib/crosstool-ng-1.23.0-rc2/scripts/build/libc/mingw.sh: line 212: [: =: unary operator expected
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.
