+hack gcc-5.3 miscompiles crt* leading to ctor/dtor related crashes

+descr
+ GCC assumes non-constant data is constant and assumes that it
+ can generate direct calls out of the ctor/dtor space, which
+ generally breaks their usage. On SPARC, an explicit call to
+ 0 is generated as "clr %g1; call %g1", for example.
+
+ Compiling with -O1 fixes this problem.
