Ah, yes, I forgot about that. The latest version of binutils changed some
defaults. What happens is this:

libb.so links to liba.so
A program uses symbols from liba.so and libb.so. With the old binutils it
was ok to just add '-lb' when linking. liba.so was picked up indirectly.
With the new binutils it fails with the errors you're seeing. The real
solution would be to fix all packages with this problem. However this is a
lot of work, so for now, you can get the old behaviour by setting:
PTXCONF_TARGET_EXTRA_LDFLAGS="-Wl,--copy-dt-needed-entries"
in the platformconfig.
