Subject: [PATCH] Compile with libc's without cispeed / cospeed
Some libc implementations (e.g. musl) do not define the cispeed and
cospeed struct termios fields. So we have to check the
_HAVE_STRUCT_TERMIOS_C_ISPEED and _HAVE_STRUCT_TERMIOS_C_OSPEED
macros. If not defined, we disable custom baudrate support.
