the default spec of passing --relax, --mifc, and --mex9 to linker.

/* The option -mno-ctor-dtor can disable constructor/destructor feature
by applying different crt stuff. In the convention, crt0.o is the
startup file without constructor/destructor;
crt1.o, crti.o, crtbegin.o, crtend.o, and crtn.o are the
startup files with constructor/destructor.
Note that crt0.o, crt1.o, crti.o, and crtn.o are provided
by newlib/mculib/glibc/ublic, while crtbegin.o and crtend.o are
currently provided by GCC for nds32 target.
For nds32 target so far:
If -mno-ctor-dtor, we are going to link
"crt0.o [user objects]".
If -mctor-dtor, we are going to link
"crt1.o crtbegin1.o [user objects] crtend1.o".
Note that the TARGET_DEFAULT_CTOR_DTOR would effect the
default behavior. Check gcc/config.gcc for more information. */
