Subject: alpha: don't reference obsolete termio struct for TC* constants
Origin: https://git.kernel.org/linus/9aeed9041929812a10a6d693af050846942a1d16
Similar in nature to ab107276607af90b13a5994997e19b7b9731e251. glibc-2.42
drops the legacy termio struct, but the ioctls.h header still defines some
TC* constants in terms of termio (via sizeof). Hardcode the values instead.
This fixes building Python for example, which falls over like:
./Modules/termios.c:1119:16: error: invalid application of 'sizeof' to incomplete type 'struct termio'
