Remove the use of gcc-specific flags.

And don't regenerate amqp_framing.[ch] if the source hasn't changed.

Without the patch to connection.c, we get

    "Modules/_librabbitmq/connection.c", line 465: reference to static identifier "AMQTable_toPyDict" in extern inline function

    "Modules/_librabbitmq/connection.c", line 685: reference to static identifier "PyDict_ToAMQTable" in extern inline function

from Studio.  These are new since 0.9.9, where we didn't have this problem.

Not sure what the right fix is.

Finally, we inherit CFLAGS and LDFLAGS from the environment rather than

using what Python was compiled with. In particular, Python 2.7 in

Userland currently has some undesired settings such as including

/usr/gnu/lib in the RUNPATH.
