None of the bare metal C library choices (avr-libc, newlib) support
installing into sysroot. Nor does it make any sense, since sysroot
implies a file system, which in turn implies an OS.
Make them configurable, default to y when build!=host (i.e.
canadian or cross-native) because we don't know what libraries the host
will provide. GLIBC, as previously, selects them explicitly.

- No new releases in almost 10 year.
- No public bug tracker or VCS.
- No responses from maintainer over sent patches.
RIP, dmalloc.

This is workaround, as more packages require similar tweaks (some
depend on X_Y_Z_or_later config variables either in kconfig, or in
the build scripts.
We should have a CT_CompareVersion, that will apply the default
or per-package method of comparison.

In case of bare metal, newlib is built without any syscalls,
and dmalloc fails to link with undefined references to _exit,
fstat, open, sbrk and so on.
Same for DUMA: depends on <memory.h>, not available with newlib.

To build uClibc correctly we need correct endianness selected in the
crosstool-NG. Xtensa cores may be little- or big-endian, but this
property is static. The toolchain knows the core endianness and doesn't
need options to select it.
Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty
CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to
the TARGET_CFLAGS, as it's not supported by gcc. Specify empty
CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the
TARGET_LDFLAGS as they are ignored. Select big-endian in the example
xtensa-unknown-linux-uclibc configuration.
This fixes uClibc toolchain build for little-endian cores.

Allow selection of make/m4/... version. Support imports of new versions
via addToolVersion.sh. Import newest versions of the companion tools.
One non-trivial change is the handling of make versions. Existing code
was not handling make companion tool as described (see the previous
commit). However, since most modern systems have make 4.x, that previous
commit made crosstool-ng always build make as a companion tool.
This traces back to the commit dd15c93 from 2014. That commit's log message
says that actually it was 3.81 which broke the build for certain component
(it was originally breaking eglibc, but I noticed it was breaking current
glibc on powerpc64), and introduced an option to force using 3.81 by
"components that really need it". It looks like in 2.5 years we haven't
seen any such components that really need make 3.81, and (given that make
has already had a few releases since 3.81) we're unlikely to see them
in the future.
Hence, the configure check is changed from "exactly 3.81" to "3.81 or newer".
In its current form, configure will accept make 3.80+, and will not require
make as a companion tool for 3.81+. We might want to bump the latter check
to even newer version given the claim from dd15c93. Killed
COMP_TOOLS_make_3_81_NEEDED.
Anyway, I retained 3.81 just in case; ditto for m4 1.14.3, autoconf 2.65
and automake 1.11.1.

1.0.18 changed the dependencies for the static libraries, notably
in libc/Makefile.in. This resulted in packing a lot of unrelated
stuff into libc.a, including (sic!) a nested .a library and stuff
from other libraries such as libdl. This results in a failure to
statically link with thus created libc.a:
.../libc.a(libdl.os):(.literal+0x74): undefined reference to `_dl_tlsdesc_return'
This was breaking xtensa-*-uclibc sample.

1.0.15 only kept a single LINUXTHREADS option, and renamed it, making it
no longer option-compatible with uClibc.
The option for "1.0.14 or later" version of uClibc-ng is not currently
used; rename it to "1.0.15 or later" and use it to handle newer
uClibc-ng's linuxthreads.
m68k happens to be the only sample using linuxthreads.
