This issue was reported by @paper42, who is using Void Linux with musl
to compile OpenWrt and its packages and found out it is not possible to
compile U-boot for Turris Omnia (neither any other).
It fixes following output:
```

Subject: [PATCH] tools: termios_linux.h: Fix compilation on non-glibc systems

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