sparc: drop UNIX98_PTYS from arch Kconfig
We have it in drivers/char/Kconfig There is no need to ask twice Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

270 A pseudo terminal (PTY) is a software device consisting of two
271 halves: a master and a slave. The slave device behaves identical to
272 a physical terminal; the master device is used by a process to
273 read data from and write data to the slave, thereby emulating a
274 terminal. Typical programs for the master side are telnet servers
275 and xterms.
276
277 Linux has traditionally used the BSD-like names /dev/ptyxx for
278 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
279 has a number of problems. The GNU C library glibc 2.1 and later,
280 however, supports the Unix98 naming standard: in order to acquire a
281 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
282 terminal is then made available to the process and the pseudo
283 terminal slave can be accessed as /dev/pts/<number>. What was
284 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
285
286 The entries in /dev/pts/ are created on the fly by a virtual
287 file system; therefore, if you say Y here you should say Y to
288 "/dev/pts file system for Unix98 PTYs" as well.
289
290 If you want to say Y here, you need to have the C library glibc 2.1
291 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
292 Read the instructions in <file:Documentation/Changes> pertaining to
293 pseudo terminals. It's safe to say N.
