no (sorry - long day, and I was not making myself clear).  The issue
to be worked around is that the ncurses library is built in part from
some source-files that are generated by programs built in that directory.
So the HOSTCC variable in ncurses/Makefile has to be a compiler that
builds programs for the current platform - since they're run immediately.
There is a configure-option (--with-build-cc) which can be used to
specify the compiler to use.  The configure script cannot simply guess
which one to use, since the compiler that has been chosen by the
script for general purposes is the cross-compiler.
