      "message": "Fix x86_64 build, clean up intermediate libraries.\n\nThe x86_64 build was failing because clone.S had a call to __thread_entry which\nwas being added to a different intermediate .a on the way to making libc.so,\nand the linker couldn\u0027t guarantee statically that such a relocation would be\npossible.\n\n  ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against \u0027__thread_entry\u0027 which may overflow at runtime; recompile with -fPIC\n\nThis patch addresses that by ensuring that the caller and callee end up in the\nsame intermediate .a. While I\u0027m here, I\u0027ve tried to clean up some of the mess\nthat led to this situation too. In particular, this removes libc/private/ from\nthe default include path (except for the DNS code), and splits out the DNS\ncode into its own library (since it\u0027s a weird special case of upstream NetBSD\ncode that\u0027s diverged so heavily it\u0027s unlikely ever to get back in sync).\n\nThere\u0027s more cleanup of the DNS situation possible, but this is definitely a\nstep in the right direction, and it\u0027s more than enough to get x86_64 building\ncleanly.\n\nChange-Id: I00425a7245b7a2573df16cc38798187d0729e7c4\n"
