It's not obvious because the tests are in kernel32, but we are
definitely supposed to set it:

../../../tools/runtest -q -P wine -T ../../.. -M kernel32.dll -p kernel32_test.exe thread && touch thread.ok
thread.c:1915: Test failed: expected 0x20301 got 0x80020301
thread.c:1916: Test failed: expected 0x70000c60 got 0x1f800c60
thread.c:1926: Test failed: expected 0x20301 got 0x80020301
thread.c:1927: Test failed: expected 0x70000c60 got 0x1f800c60
make: *** [Makefile:948: thread.ok] Error 4

Looking at your test case, it may be that we shouldn't set it when the
FPU control word didn't change. You should extend the tests in thread.c.
