If C++ headers such as <cstdlib> or <thread> are used, GCC 6 will include /usr/include/stdlib.h (instead of stdlib/stdlib.h in the glibc source directory), and this turns up as a make dependency. An implicit rule will kick in and make will try to install stdlib/stdlib.h as /usr/include/stdlib.h because the target is out of date. This commit switches to <stdlib.h> and <pthread.h> instead of <cstdlib> and <thread>.
