Binutils change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF*
relocation offsets." changed signedness of BFD_RELOC_XTENSA_DIFF*
relocations substituted for BFD_RELOC_*. This made it impossible to
encode arbitrary 8-, 16- and 32-bit values, which broke e.g. debug info
encoding by .loc directive. Revert this part and add test.

This updates patches for 2.26. Most notably, the removal of the xtensa
patches which seem to be upstream in binutils now.

If CPATH, C_INCLUDE_PATH, CPLUS_INCLUDE_PATH, or OBJC_INCLUDE_PATH are set, bail out.
These environment variables are known to break crosstool-ng's build.
This closes#327

OSX SDK has a declaration for `wcsncasecmp` since 10.7, which conflicts with
the definition provided by the patch for binutils.

As crosstools-ng only support GCC >= 4.8 we do not need libelf for gcc. GCC dropped this dependency with 4.6.

elf2flt is now hosted on github here:

But, until arm support is upstream, we'll switch to Waldemar Brodkorb
version of elf2flt.

I was noticing that $extra_user_env was inconsistently used in
100-gcc.sh. I don't feel comfortable having just any make flag or
environment variable passed to make from a config file. If a specific
option needs to be passed to make for gcc, then a specific kconfig
option should be added for that make flag/option/env.

The two gcc backend functions are getting very close to being duplicated
code. To help in the process of merging the two backends, this change
syncronizes the two functions so they are easier to diff.
This commit has no functional changes.

If destdir was / and prefix began with /
then we would attempt to install libelf
to a path beginning with // which is a
UNC path on Cygwin. This is generally
incorrect.

On Windows a build failure can be triggered during the
build of the static iconv if a dynamic iconv is already
present:
There's a circular dependency between libiconv and gettext
which (on a system with a dynamic gettext (and thus iconv)
installed in the system prefix) causes a failure to build
iconv.exe statically if it is built with nls ..
.. Which needs gettext
.. which depends on libiconv
.. so libtool finds a dynamically linked libgettext.la
.. and therefore presents ld with the dll import library
libiconv.dll.a when linking iconv.exe
.. as well as the static libiconv.a that it has just built!
.. leading to multiply defined symbols from iconv.
Therefore, we build it without nls. If it later turns out
that we need it to be built with nls, then I will have to
build it in two passes (common practice when bootstrapping
GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

Cygwin follows POSIX IEEE Std 1003.1, 2004 Edition spec
for the select() fuction as described at:
http://pubs.opengroup.org/onlinepubs/009695399/functions/pselect.html
.. so we must #include <sys/select.h> for the declaration.

Define PICFLAG, UNDEFINEDPREAMBLE and UNDEFINEDCODE to nothing since Windows
doesn't have -fPIC (GCC warns) and can't handle undefined variable references
(which are not needed anyway).

Build shared builds for host unless CT_STATIC_TOOLCHAIN.
In all other situations, build statically, as before.
It is necessary that the static/shared-ness of expat matches
that of gettext on Cygwin/MinGW-w64 as they can't be linked
together if they don't match, so we follow the same logic.

The buildroot patches have xtensa for the supported versions of binutils
we use, and a few others that might help us keep away from host
polution.

Since older GCC versions have been removed, older versions of binutils
are not needed.
This commit removes these older versions.
