Consolidate strerror handling, as well as getcwd/getwd.
* configure.in (GCC_NEED_DECLARATIONS): Add strerror, getcwd and
getwd.
* acconfig.m4: Add stubs for NEED_DECLARATION_STRERROR,
NEED_DECLARATION_GETCWD and NEED_DECLARATION_GETWD.
* cccp.c: Remove strerror()/sys_nerr/sys_errlist decls.
(my_strerror): Add prototype and make it static.
* collect2.c: Likewise.
* cpplib.c: Likewise.
* gcc.c: Likewise, but keep `my_strerror' extern.
* protoize.c: Likewise.
* pexecute.c (my_strerror): Add argument to prototype.
* system.h: Add prototypes for getcwd, getwd and strerror. Add
extern decls for sys_nerr and sys_errlist. Make abort decl
explicitly extern.
* getpwd.c: Remove decls for getwd and getcwd.
