Mark _vscprintf() and _scprintf() functions with attribute pure as their
return value depends only on passed arguments.
In function __ms_vsnprintf() check only for n==0 and move _vscprintf() call
at the end of function. This allows LTO to optimize out _vscprintf() call
from __ms_vsnprintf() functi
MinGW-w64 has same startup files for crtdll.dll and msvcrt.dll and defining
-D__CRTDLL__ or -D__MSVCRT__ has no effect on built *crt*.o files, they are
same. So build startup files only once and create other as copy from the
first one. Also remove -D__CRTDLL__ and -D__MSVCRT__ as they are not used
Currently v*scanf functions are broken and crash when are called with more
than 30 arguments in va_list. This is because va_list v*scanf functions are
redirected to variadic *scanf functions and this redirect implemented in
scanf.S file has fixed limit for 30 arguments.

Import library libcrtdll.a (for crtdll.dll runtime library) compiled during
mingw-w64 build process is currently broken and cannot be used for linking
executable applications.
Trying to do it results in following linker errors:
