Can't compile v5-34-22 on MacOS X in "configure mode"

Hi,

I saw that v5-34-22 came out this evening, so I tried to install it on my usual test platforms. (It has a fix important for ATLAS ROOT I/O...)

While it compiled just fine on Ubuntu 14.04, on my Mac laptop the compilation failed with:

/Users/krasznaa/Development/ROOT/root-v5-34-22/core/meta/src/TCint.cxx:2430:4: error: thread-local storage is

      unsupported for the current target

   thread_local static TString stldir;

I used the following to configure the compilation:

./configure --with-xrootd=/usr/local/xrootd/4.0.3 --disable-fink --all --enable-libcxx --enable-c++11

While ROOT 5 is far from being mission critical for ATLAS on MacOS X (our I/O on MacOS X only works with ROOT 6 by now), this is definitely something weird... :-/

Cheers,
Attila
