ignore libhugetlbfs warnings
There's a problem that has manifested on Cray Linux Environment systems when trying to build CMake with a craype-hugepages modulefile loaded on a front-end node where explicit hugepages are not implemented. We need to be able to ignore warnings emitting from libhugetlbfs [nid000xx:xxxxx]: WARNING: New heap segment map at 0x10000000 failed: Cannot allocate memory
in the bootstrap process to achieve an installation, so the hugepages modulefile can accommodate building a chain of software with the same dependency tree for code teams at LANL. @chuck.atkins @purpleKarrot
