* buildsym.h: Add processing_acc_compilation flag.

Browse Source 
* buildsym.c (read_sun_builtin_type, read_sun_floating_type):  New.
(define_symbol):  Skip arg types in function entries.  Resolve
overloaded 'P' which acc uses for prototypes of functions called
by this file.
(read_type: 'b', 'r'):  Handle Solaris2 builtin types.

* minsyms.c (prim_record_minimal_symbol_and_info):  Hack to
save size of ELF symbols.  FIXME.
* tm-sun4os5.h:  Rename to tm-sun4sol2.h.  Update defines for Sol2.
* xm-sun4os5.h:  Rename to xm-sun4sol2.h.  Hack more defines.

* config/sun4os5.m[ht]:  Rename to config/sun4sol2.m[ht]; new xm, tm.
