support: Build with exceptions and asynchronous unwind tables [BZ #30587]

Browse Source 
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".
