It thought, I'd retry the same procedure with gcc 8.2.0 today. This
target header issue is indeed gone -- the build just works. Alas, the
resulting compiler does not :(.

$ ~/gcc8/bin/g++ -x c++ x.c
during IPA pass: inline
x.c:13:1: internal compiler error: in inline_small_functions, at
ipa-inline.c:1865

Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.

For this program:

#include <stdio.h>

#include <iostream>

using std::cout;
using std::endl;

int main()
{
    printf("hello!\n");
    cout << "hello2!" << endl;
    return 0;
}
