It's a board and device support package which depends on board and 
device specific features and files including kernels, device trees, root 
file systems, and firmware in specific locations so can not be built in 
the Cygwin POSIX environment without adaptation:

"The development of U-Boot is closely related to Linux: some parts of
the source code originate in the Linux source tree, we have some
header files in common, and special provision has been made to
support booting of Linux images."

You could look at using a Linux emulator like WSL or VM like VirtualBox.

You may wish to look at RTEMS and other OSes which use newlib (in common 
with Cygwin) to develop similar systems.
