glibc: Migrate eglibc 2.19 -> glibc 2.20

- This is a big swoop change where we switch to using glibc
- option-groups are forward ported
- cross-localedef is extracted out from eglibc and hosted
  at github.com/kraj/localedef, its used for cross-localedef
  recipe
- Other non ported patches from eglibc are forward ported
  ppc8xx cache line workaround
  SH fpcr values
  dynamic resolver
  installing PIC archives is there but is not applied
  libc header bootstrap

- Delete eglibc recipes we moved back to using glibc now
- Fix ppc/e500 build

- Fix crypt module build when options are used
- Fix fnmatch build when options OPTION_EGLIBC_LOCALE_CODE is unset
  HAVE_MBSTATE_T and HAVE_MBSRTOWCS should be defined conditionally
  based upon OPTION_EGLIBC_LOCALE_CODE being set/unset
- Move the ports/ patches to relevant files now that ports is gone

-Hi,
-
-This patch adds 'make menuconfig' support to EGLIBC.
-
-
-EGLIBC can re-use the Linux kernel kconfig host tools ('conf' and 'mconf') unmodified, by passing appropriate environment variables and with some pre- and post-processing on the input/output config files.
-
-There are three new make targets supported, which all are defined in the new libc/options-config/Makefile, which is included by the top-level libc/Makefile:
-
-- 'make defconfig'. This passes 'libc/option-groups.defaults' to 'conf' as a default config, and outputs 'option-groups.config' to the top-level build directory, which will be the same as the default config.
-
-- 'make config'. This is the same line-oriented interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
-
-- 'make menuconfig'. This is the same menu-based interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
-
-
-Pre-Processing:
-
-
-The Linux kernel kconfig tools expect a prefix of "CONFIG_" on all config option names, but EGLIBC expects a prefix of "OPTION_". The pre-processing script, libc/options-config/config-preproc.pl, simply replaces "CONFIG_ with "OPTION_" in the given config file. The libc/options-config/Makefile passes the script output to a temporary config file, which is then passed to 'conf' or 'mconf'.
-
-Post-Processing (libc/options-config/config-postproc.pl):
-
-
-- Disabled options are output as a comment line of the form "# CONFIG_FOO is not set". This needs to be changed to an explicit "CONFIG_FOO=n" in order to be compatible with 'option-groups.awk' which generates the option-groups.h header.
-
-- "CONFIG_" prefix is changed back to "OPTION_".
-
-
-- The kconfig tools will not output anything for options that depend on a parent option, when the parent option is disabled. This implicit disable must be converted to an explicit "CONFIG_FOO=n" in order to be compatible with the way EGLIBC overrides the default option settings in 'libc/option-groups.defaults' with those in 'option-groups.config'.
-
-
-A new configure option, '--with-kconfig=<PATH>', tells EGLIBC where to find the pre-built 'conf' and 'mconf' host tools from Linux kernel builds.
-
-libc/EGLIBC.cross-building is updated to include instructions for using '--with-kconfig' for the final EGLIBC build, and shows how and when to run 'make *config'.
-
-libc/EGLIBC.option-groups is updated to include new information on the menuconfig support.
-
-Thanks,
-
-attached is the updated patch to address above issues.
-
-Steve

-+Note the additional '--with-kconfig' option. This tells EGLIBC where to
-+find the host config tools used by the kernel 'make config' and 'make
-+menuconfig'.  These tools can be re-used by EGLIBC for its own 'make
-+*config' support, which will create 'option-groups.config' for you.
-+But first make sure those tools have been built by running some
-+dummy 'make *config' calls in the kernel directory:

-+    $ cd $obj/linux
