package/libcodec2: new package

[Thomas:
 - replace patches from Bernd by patches that are Git formatted and
   have a chance of being upstream.
 - remove the no longer necessary post configure hook to build
   generate_cookbook for the host
 - pass --disable-unittests to disable unit tests.]

+Subject: [PATCH] Use the native compiler to build generate_cookbook
+
+The generate_cookbook binary needs to be executed at build time. When
+cross-compiling, this means that it should be built with the native
+compiler rather than the cross-compiler.
+
+To achieve this, this commit imports the AX_CC_FOR_BUILD autoconf
+macro from the GNU Autoconf Archive project, and adjusts
+src/Makefile.am to use CC_FOR_BUILD to build generate_cookbook.
+
+Based on initial work by Bernd Kuhls.
