Subject: Fix klibc Debian specific build trouble

Simply remove the headers_install invocation and rely on linux-libc-dev.

With these changes:

(the extra chmod was needed to allow for umask > 022) I could compile,
link and run this program:

#include <unistd.h>

int main(void)
{
	write(1, "Hello world\n", 12);
	return 0;
}
