What on earth this note has to do with this build problem?

You configured the GCC for Cygwin $host, not for MinGW $host
('i686-mingw32'). So you MUST have the Cygwin GCC as the 'gcc'
which compiles the GCC sources !

Very simply: If you want the 'v850-elf' target GCC for the
Cygwin $host, then use the Cygwin target GCC with its headers
and libraries! If you want the 'v850-elf' target GCC for the
MinGW $host, then please use the MinGW target GCC with its
headers and libraries! And in this MinGW case also use the
'--host=i686-mingw32' when configuring the GCC...
