Document/implement a way to disable manifest

[justanotheranonymoususer]

In the README you say:

Starting from release 9.2.0, both editions of TDM-GCC come with a windows-default-manifest package. If you install it (which is recommended)

Recommended doesn't sound like mandatory, so I didn't install it. Now, strange things happen:

Compiling an exe - without a windows-default-manifest package

C:\test>g++.exe exe.cc 
c:/compiler/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find default-manifest.o: No such file or directory
collect2.exe: error: ld returned 1 exit status

The error message is not very clear. I'd expected the compiler to succeed and just not add a manifest. I also didn't find a way to disable the manifest.

Compiling a dll - without a windows-default-manifest package

C:\test>g++.exe dll.cc -shared

It works, no manifest. Great.

Compiling an exe - with a windows-default-manifest package

It works and a manifest is added. What if I don't want it?

Compiling a dll - with a windows-default-manifest package

It works and a manifest is not added. What if I do want it?
