Sascha, you need to build ncurses with the buildroot/cross build first,
then build Xorg.
It's not obvious, but the buildroot is building without using the
additional things you've installed for your host system. Those things
-- such as ncurses -- give your host system the ability to do ncurses et
al. They are (I assume) i386/glibc. Although buildroot is capable of
cross-compiling something that is a different architecture, you're doing
an i386/uClibc build. Nevertheless, you still need to build ncurses
inside buildroot to install the library in the right subdirectory so
that it will be found during the link phase. This is a problem my
(recently former) company's customers see, and the sole reason I send
them to buildroot -- missing libraries, and the fact that buildroot will
do the right thing.
try adding ncurses in the "packages" section of "make menuconfig", then
"make ncurses", then your existing build. Later, you'll want to add
ncurses as a dependency of Xorg.
(I'm guessing on these make menuconfig option and make target due to the
pattern of buildroot)
