[PATCH v1 5/6] Adjust DLL import/export implementation for AArch64

[Evgeny Karpov <Evgeny.Karpov@microsoft.com>]

The DLL import/export mingw implementation, originally from ix86, requires
minor adjustments to be compatible with AArch64.

gcc/ChangeLog:

	* config/mingw/mingw32.h (defined): Use the correct DllMainCRTStartup
	entry function.
	* config/mingw/winnt-dll.cc (defined): Exclude ix86-related code.
