It looks to me like the same would probably occur on the target.
The .so devel symlinks should be in ${libdir} not ${base_libdir} since
the latter is indeed not in the linker's standard search path.

There are some commented-out bits in bitbake.conf which would put it
there:

#export TARGET_LDFLAGS = "-L${STAGING_DIR_TARGET}${libdir} \
#                         -Wl,-rpath-link,${STAGING_DIR_TARGET}${libdir} \
#                         -Wl,-O1"

but even then it would still fail for on-target builds that don't use
bitbake and I think we should just fix ncurses to install itself into
the correct place.  Or everyone should use micro and avoid this whole
class of problems. :-)
