* cppdefault.c: Define cpp_PREFIX, cpp_PREFIX_len, and
gcc_exec_prefix.
(cpp_relocated): New function.
* cppdefault.h: Declare cpp_PREFIX, cpp_PREFIX_len, gcc_exec_prefix
and cpp_relocated.
* Makefile.in (PREPROCESSOR_DEFINES): Add -DPREFIX option.
* c-incpath.c (add_standard_paths): Call cpp_relocated. If relocated,
replace configured prefix with gcc_exec_prefix.
