217ab9879c * Enabled internal handling of Abs(longint) for all targets. It has been implemented in cross-platform way ages ago (see tcginlinenode.second_abs_long), but not enabled on MIPS,SPARC and m68k. 
- RTL: removed MIPS,SPARC and m68k-specific implementations of Abs(longint), and marked the generic one as  required for bootstrapping purposes only.

0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp. 
+ m68k/mathu.inc: added stub implementations for missing functions.

8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.
