judging by your initial ncurses build error, you haven't successfully
xmerge'd anything into SYSROOT, so all you had to do was change CHOST in
${SYSROOT}/etc/make.conf, then try xmerge ncurses again.

crossdev doesn't use SYSROOT, it creates it. So there is no need to set it.

Did you repeat Section 3 of the cross-development guide after blowing
away SYSROOT with crossdev -C <target>? And set CHOST correctly?
