This prevents a spurious message building a cross-compiler when target
libc is not installed yet:
cc1: error: no include path in which to search for stdc-predef.h
As stdc-predef.h was added to define __STDC_* macros by libc, it's
unlikely the header will ever contain some bad definitions w/o "__"
prefix so it should be safe.
gcc/ChangeLog:
PR other/109522
* Makefile.in (s-macro_list): Pass -nostdinc to
$(GCC_FOR_TARGET).
