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

+eglibc-nativesdk: Fix buffer overrun with a relocated SDK
+
+When ld-linux-*.so.2 is relocated to a path that is longer than the
+original fixed location, the dynamic loader will crash in open_path
+because it implicitly assumes that max_dirnamelen is a fixed size that
+never changes.
+
+The allocated buffer will not be large enough to contain the directory
+path string which is larger than the fixed location provided at build
+time.
