See mingw-w64-docs for help on building. A lot of LFS doesn't apply to

You are missing the CRT, see mingw-w64-crt.

You'd run into problems setting AR and RANLIB like that, let autotools
do its job.

Posix thread isn't for the faint hearted, you need to bootstrap
winpthread dll with libgcc, but DLLs can't be built without libgcc. I
suggest you remove --enable-threads=posix unless you have some special
needs, let gcc use the more tested win32 threads.

You are also missing essential options like
--enable-fully-dynamic-strings and --enable-sjlj-exceptions, you are
likely to break ABI from the auto builds. Finally, remove
--enable-__cxa_atexit, it will only work for glibc based hosts as far as
I know.
