   9 TCGETS2 is defined in header file asm/ioctls.h provided by linux kernel.
  10 On glib systems it is automatically included by some other glibc include
  11 header file and therefore TCGETS2 is present in termios_linux.h when
  12 linux kernel provides it.
  13
  14 On non-glibc systems (e.g. musl) asm/ioctls.h is not automatically included
  15 which results in the strange error that BOTHER is supported, TCGETS2 not
  16 defined and struct termios does not provide c_ispeed member.
  17
  18     tools/kwboot.c: In function 'kwboot_tty_change_baudrate':
  19     tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed'
  20       662 |   tio.c_ospeed = tio.c_ispeed = baudrate;
  21           |      ^
  22
  23 Fix this issue by explicitly including asm/ioctls.h file which provides
  24 TCGETS2 macro (if supported on selected architecture) to not depending on
  25 glibc auto-include behavior and because termios_linux.h requires it.
  26
  27 With this change it is possible compile kwboot with musl libc.
