The interesting part would have been newlib.

Vanilla newlib-1.13.0 isn't sufficient for rtems-CVS, vanilla-1.14.0
should be OK for "C", but currently suffers from a problem with its
interaction with rtems in "C++" (The cause is known, a proper fix still
has to be implemented).

This is the culprit                                           ^^

_This_ issue is known! 

You can't build a plain "gen5200" BSP due a design limitation lurking
inside of this BSP. You should only be able to build the pm520_cr825 and
pm520_ze30 BSP, which are derived from it.

I thought I already fixed this issue (I think committed the patches
yesterday). May-be I missed something, may-be you need a "cvs update".
