Subject: include/bits/sigstksz.h: Avoid #elif IS_IN (libsupport)

include/bits/sigstksz.h: Avoid #elif IS_IN (libsupport)

GCC 4.9 issues an error when generating misc/check-installed-headers-c.out:

In file included from ../signal/signal.h:328:0,
                 from ../include/signal.h:2,
                 from ../misc/sys/param.h:28,
                 from ../include/sys/param.h:1,
                 from /tmp/cih_test_e156ZB.c:10:
../include/bits/sigstksz.h:5:7: error: "IS_IN" is not defined [-Werror=undef]
 #elif IS_IN (libsupport)
       ^

Use "#else" instead.
