We trend to solve this issue like what RISC-V did, force 
gcc_cv_initfini_array=yes in config.gcc when glibc is built.
The first way may take quite a long time to find out what compilation test
is required to get things right. We'v got some question about what compilation
test should be like for C-SKY. We'v got several other C library do not use 
init-array at present. When gcc is built first time we are not able
to find out whether the C library want init-array or not, if gcc is not
rebuilt for C++, init/fini will never be called. Even if gcc is rebuilt,
we can not execute test program if it is cross-compiled. We may try to make 
init-array check in configure work later when we find ways to solve the
issues above.
