[00/25] Patches for building with mingw/gcc msvc/clang-cl

  I split it into small patches for easier to review

Yonggang Luo (25):
  Rename 'hello2.spec.' -> 'hello2.spec' 'hello3.spec.' -> 'hello3.spec'
  ignore build directory
  libebl: There is no need #include <dlfcn.h> in eblclosebackend.c and
    eblopenbackend.c
  libelf/libdwfl: Remove "#define LIB_SYSTEM_H 1" in libelf_crc32.c and
    libdwfl_crc32.c
  use #include <system.h> instead platform depended header <endian.h> in
    libdw/memory-access.h
  move platform depended include into system.h of libebl
  move platform depended include into system.h of libasm, libcpu, libdw,
    libdwfl and libdwelf
  Use configure to detect HAVE_DECL_MMAP and use it for system doesn't
    provide sys/mman.h
  include libgen.h in system.h
  libcpu: Remove the need of NMNES by using enum
  libcpu: Use __asm instead asm that can be recognized by both clang-cl
    and gcc
  libcpu: Use "#define FCT_mod$64r_m FCT_mod$r_m" is enough and can be
    recognized by clang-cl on windows in i386_data.h
  libdw: typeof -> __typeof that can be recognized by both clang-cl and
    gcc
  libdw: check __OPTIMIZE__ in dwarf_whatattr.c and dwarf_whatform.c to
    match the header
  lib: Implement error properly even when not HAVE_ERR_H
  libeu: Move the implementation of  pwrite_retry, write_retry and
    pread_retry from header to source
  libelf: uid_t, gid_t and mode_t are not comes with msvcrt, so using
    long/unsigned long instead on win32
  lib: Use NOT_HAVE_LIBINTL to guard #include <libintl.h>
  libelf: F_GETFD may not predefined with msvc/mingw, guard the usage of
    it
  Add function sys_get_page_size to replace platform dependent sysconf
    (_SC_PAGESIZE)
  libasm: stdio_ext.h are not present on win32
  libebl/libdwelf: define ssize_t and pid_t for MSVC within installed
    header libdwelf.h and libebl.h
  libasm/debuginfod: fchmod doesn't present on win32
  lib: isatty is not available on windows
  Fixes building with msvc/clang mingw/gcc
