bfd too #. * ldexp.c, ldlang.c: now build memory shape tree in obstacks rather than with raw malloc, makes it easier to track where memory is going. * ldsym.h, ldsym.c: create obstack for all global symbols too. * ldwrite.c (ldwrite): moved malloc so only used when needed. * sa29200-sc.sh: added support for .lit, data1 and data2 sections.
