Steps to reproduce

On OpenBSD:

AUTOCONF_VERSION=2.71 AUTOMAKE_VERSION=1.16 \
		config_args='--with-ffi-includes=/usr/local/include 
			--with-ffi-libraries=/usr/local/lib 
			--with-gmp-includes=/usr/local/include 
			--with-gmp-libraries=/usr/local/lib 
			--with-iconv-includes=/usr/local/include 
			--with-iconv-libraries=/usr/local/lib 
			--with-system-libffi ' \
    ./validate --fast "$@"

Expected behavior

Build working GHC.
