Then when I do

# header search path is -isystem ./include
ln -s /usr/include/sys ./gcc/include/sys
ln -s /usr/include/machine ./gcc/include/machine
ln -s /usr/include/ppc ./gcc/include/ppc
ln -s /usr/include/unistd.h ./gcc/include/unistd.h
ln -s /usr/include/_types.h ./gcc/include/_types.h

it succeeds to the next missing header

enable-execute-stack.c:27:10: fatal error: stdlib.h: No such file or directory
 #include 
  ^~

Why I need to do this by hand?

The same system’s `as` eats both of ppc and ppc64 assembly. It looks like that
build machinery of GCC just can’t locate it. Plus there’s another problem with

enable-execute-stack.c:25:10: fatal error: sys/mman.h: No such file or
directory

When I change

ORIGINAL_AS_FOR_TARGET=""

to

ORIGINAL_AS_FOR_TARGET="as"

inside gcc/as shell script, it succeeds, but not for long

Do you have an assembler for the cross-target installed?

assembly of conftest.c

It really can’t assemble main() { return 0; }
