* system.h: Include libiberty.h.
* c-aux-info.c: Remove prototypes for concat/concat3. Change
function `concat' from fixed parameters to variable parameters,
as is done in libiberty. All callers of concat/concat3
changed to use the new `concat' with variable args.
* cccp.c: Remove things made redundant by libiberty.h and/or
conform to libiberty standards.

conform to libiberty standards.
(fatal): Fix const-ification of variable `format' in
!ANSI_PROTOTYPES case.
* prefix.c: Remove things made redundant by libiberty.h and/or
conform to libiberty standards.
