Add the full crosstool-NG sources to the new repository of its own.
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(

38 The thread_offsetof change just mirrors what Alan Modra did to NPTL
39 tcb-offsets.sym. Apparently for GCC 4 an offsetof like expression,
40 but not really offsetof, is no longer constant folded and therefore
41 not suitable for "i" constraint.
43 The ELF_MACHINE_NO_RELA change is needed to avoid
44 rtld.c: In function '_dl_start':
45 dynamic-link.h:50: error: nested function 'elf_machine_rela_relative' declared but never defined
46 dynamic-link.h:47: error: nested function 'elf_machine_rela' declared but never defined
48 rtld.c first includes dl-machine.h without RESOLVE_MAP
49 and without RTLD_BOOTSTRAP defined. This means that ELF_MACHINE_NO_RELA
50 is not defined on i386/arm. Later on it defines RESOLVE_MAP
51 and RTLD_BOOTSTRAP and includes dynamic-link.h which has:
52 # if ! ELF_MACHINE_NO_RELA
53 auto void __attribute__((always_inline))
54 elf_machine_rela (struct link_map *map, const ElfW(Rela) *reloc,
55 const ElfW(Sym) *sym, const struct r_found_version *version,
56 void *const reloc_addr);
57 auto void __attribute__((always_inline))
58 elf_machine_rela_relative (ElfW(Addr) l_addr, const ElfW(Rela) *reloc,
59 void *const reloc_addr);
61 and later on includes dl-machine.h which sees RTLD_BOOTSTRAP is
62 defined and defines ELF_MACHINE_NO_RELA and doesn't define
63 elf_machine_rela* nested functions.
64 But the prototypes were already defined and GCC 4 doesn't like this.
65 ELF_MACHINE_NO_RELA is only ever used in preprocessing conditionals
66 and never in defined ELF_MACHINE_NO_RELA, so the trick below
67 already defines ELF_MACHINE_NO_RELA to 1/0 depending on whether
68 RTLD_BOOTSTRAP is defined and thus the prototypes in dynamic-link.h
69 that are not desirable are gone.

73 * sysdeps/i386/dl-machine.h (ELF_MACHINE_NO_RELA): Define
74 unconditionally to (defined RTLD_BOOTSTRAP).
75 * sysdeps/arm/dl-machine.h (ELF_MACHINE_NO_RELA): Likewise.
77 * sysdeps/powerpc/tcb-offsets.sym (thread_offsetof): Rework for GCC 4.
