(A couple tips:
add set -x to your build scripts in the future, makes the logs easier to read.
add set -e as well, so the script aborts at first error.)

The thing to do here is to read gdb's configure script to see where it is
outputting that error message, "configure: error: no termcap library found".
That will tell you how it's looking for the library.

Another thing you could do is use your cross-compiler to do a trivial program
that uses ncurses.  If it doesn't compile, or doesn't link, you have
installed ncurses wrong.

If you copied the files by hand, you probably installed them wrong.
It's better form to use ncurses' "make install" rule to install the files.
You may need to override the destination directory when you do this.
To tell how to do this, either read the ncurses Makefile, or look
at how some other package cross-builds and installs ncurses.  ptxdist
does the install step like this:

make DESTDIR=$(CROSS_LIB_DIR) prefix='' exec_prefix='' install

where CROSS_LIB_DIR is $(PTXCONF_PREFIX)/$(PTXCONF_GNU_TARGET)
or something like /opt/crosstool/$(TARGET)/$(TOOLCOMBO)/$(TARGET)
