We currently define "CFLAGS += -msoft-float -fno-optimize-sibling-calls" in Makefile.compel. Makefile.compel is included into the toplevel Makefile and so changes CFLAGS which are exported to all criu and zdtm Makefiles. We must not use -msoft-float outside the compel files. E.g. otherwise for zdtm we get the following build error: uptime_grow.o: In function `main': /tmp/2/criu/test/zdtm/static/uptime_grow.c:36: undefined reference to `__floatdidf' /tmp/2/criu/test/zdtm/static/uptime_grow.c:36: undefined reference to `__muldf3' /tmp/2/criu/test/zdtm/static/uptime_grow.c:36: undefined reference to `__floatdidf' /tmp/2/criu/test/zdtm/static/uptime_grow.c:36: undefined reference to `__adddf3 Fix this and move the CFLAGS definition to the compel Makefiles. We do this by defining a new flag CFLAGS_PIE that is only used for pie code.
