libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)

When GMP is being "cross" compiled for the same architecture (i.e. build
== host) it does not pick the right compiler. Set CC_FOR_BUILD and
CPP_FOR_BUILD to override the default compiler.

... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
uClibc (non-NG) with lots of kludges removed.
There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.

Currently when building cross-canadian toolchain for macOS
the folowing error happens when GCC is configured:
|ld: illegal text-relocation to '___gmp_binvert_limb_table' in
|... /.build/... /buildtools/complibs-host/lib/libgmp.a(mp_minv_tab.o) from '___gmpn_divexact_1' in
|... /.build/... /buildtools/complibs-host/lib/libgmp.a(dive_1.o)
|collect2: error: ld returned 1 exit status
Apparently this might be solved with GMP configured with "--with-pic",
even though we're talking about static library here.
That solution was found here:

GMP's configure script tries to be too smart, and if it determines
that it's not cross-compiling it chooses gcc or cc instead of the
wrapper we create at the start of the build.

The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.
This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.
Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

We check for apps:
* make
* sed
* grep
* awk
* libtool/libtoolize
* install
* patch
* and more
...during configure. Our scripts should be consistent about using the
variables that define where the found tool was found.
Of course, we do hard-link these tools in buildtools, but that should be
a backup for the components we are building. Our scripts should always
use the tools we find.

Currently, only libelf has a for-target step - but it generalizes
the step to hook other libraries into this step.

This change updates the download locations to default to the official
download site.
For gcc and gdb, also separate out the linaro download locations so that
if you are downloading the linaro variant, it skips trying to download
from the official gcc mirror.

On some hosts, and for certain toolchains (eg. toolchain targetting
the upcoming Darwin), it may be necessary to pass arbitrary CFLAGS
and/or LDFLAGS when building the components.
And necessary infrastructure:
- EXTRA_{CFLAGS,LDFLAGS}_FOR_{BUILD,HOST} as config options
- pass those extra flags to components
Fix-up a slight typo in elf2flt at the same time (misnamed cflags).
