    support: Build with exceptions and asynchronous unwind tables [BZ #30587]
    
    Changing tst-cleanup4.c to use xread instead of read caused
    the nptl/tst-cleanupx4 test to fail.  The routines in libsupport.a
    need to be built with exception handling and asynchronous unwind
    table support.
    
    v2: Use "CFLAGS-.oS" instead of "override CFLAGS".
