Unable to build Go 1.4 Bootstrap using Intel Compilers

So I'm attempting to do the following (from https://golang.org/doc/install/source)

To build a bootstrap toolchain from source, use either the git branch release-branch.go1.4 or go1.4-bootstrap-20171003.tar.gz, which contains the Go 1.4 source code plus accumulated fixes to keep the tools running on newer operating systems. (Go 1.4 was the last distribution in which the toolchain was written in C.) After unpacking the Go 1.4 source, cd to the src subdirectory, set CGO_ENABLED=0 in the environment, and run make.bash(or, on Windows, make.bat).

And make.bat works fine under MingW64 (MSYS2) + GCC:
