Toolchain build for cp2k 3.0: elpa-2015.11.001_mt compilation fails

Hello Alfio,

compiling the toolchain failed for ELPA on two different machines: one 
running openSUSE 13.1on an AMD Opteron 6376 ("Piledriver"), another with 
openSUSE 12.2 on an Opteron 6276 ("Bulldozer"). According to Wikipedia, 
they should support AVX. I did, however, just succeed compiling the 
toolchain on an older machine with openSUSE 11.3 with an Opteron 865. 
Strangely enough, the latter CPU does not have AVX support.

Well, it seems like things work for me now on this older machine. Maybe the 
other systems are just configured in an incompatible way?
