sparc: drop UNIX98_PTYS from arch Kconfig
We have it in drivers/char/Kconfig
There is no need to ask twice

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. | ||
