      Python won't build on Solaris with dtrace support enabled.

      Solaris is one of those systems where it is necessary to generate dtrace object files with dtrace -G. While this need is included in python configure and Makefiles, it doesn't work correctly.

      First, configure tests -G support on file with not completely valid content of just BEGIN inside. Valid should have BEGIN{}. This is not a problem for systems that don't require dtrace object files as this test should fail for them anyway, however it incorrectly detects those like Solaris.

      And second, Makefile is not ready for dtrace as the DTRACE_DEPS variable doesn't include all the necessary files.

      Can this also be backported to 3.7? I just installed 3.8a3 (where it already is) and it works as expected.

      Also we are using this patch ourselves in 3.7 and it works but I guess it would be nicer to have it in upstream as well.

      No more non-security related backports to 3.7 allowed.
