gcc makefile obj and bin directories

[jeffreyscottgraham]

The compile fails because the two directories 'obj' and 'bin' are assumed to exist

[jeffreyscottgraham]

Here is a patch (it also sets CC and CFLAGS only if not already set, since some of us do not use clang)

+1, I had to create bin and obj and use CC=c++ as clang++ didn't exist. I also had to add -std=c++11 to CFLAGS as GCC warned: ./sample/example.cpp:360:120: warning: ISO C++98 does not support the '%lf' gnu_printf format

The issue is now fixed in the current head revision (although i just added the folders to the repository)
