Well, for packages that do build on noMMU platforms, we do catch such
issues thanks to the bfin-uclinux toolchain configuration that is used
on the autobuilders. But for those other packages that don't build on
noMMU, we indeed don't check properly if we're able to do a pure static
build.

Alexey has sent a patch to remove HAVE_SHARED from the uClibc
configuration when BR2_PREFER_STATIC_LIB is enabled. Maybe this will
get rid of ld.so, libdl and so on? I haven't tested yet.
