A testdir for 'cond' fails to compile on Solaris 10:
gcc -O2 -DHAVE_CONFIG_H -I. -I../../gltests -I.. -DGNULIB_STRICT_CHECKING=1
-DIN_GNULIB_TESTS=1 -I. -I../../gltests -I.. -I../../gltests/.. -I../gllib

-g -O2 -MT test-cond.o -MD -MP -MF .deps/test-cond.Tpo -c -o test-cond.o
../../gltests/test-cond.c
In file included from ./unistd.h:40:0,
from ../../gltests/test-cond.c:61:
/usr/include/unistd.h:542:23: error: macro "yield" passed 1 arguments, but
takes just 0
extern void yield(void);
^
*** Error code 1
The reason is that on Solaris, <unistd.h> declares yield(), which we have
defined as a macro in this compilation unit. This patch fixes it.

cond tests: Fix compilation error on Solaris.
* tests/test-cond.c: Include <unistd.h> before defining 'yield' as a
macro.
