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.
