pts/hpgc install fail on Power

[else58]

What is the reason for adding -march=native to the hpgc build?
That option is not available for the version of mpicxx available in Fedora 17 for Power64.

/usr/lib64/openmpi/bin/mpicxx -c -fopenmp -O3 -march=native -ffast-math -ftree-vectorize -I./src testing/main.cpp -o testing/main.o
g++: error: unrecognized command line option '-march=native'
make: *** [testing/main.o] Error 1


mpicxx version:

/usr/lib64/openmpi/bin/mpicxx --version
g++ (GCC) 4.7.2 20120921 (Red Hat 4.7.2-2)

Just for optimizing for the CPU its building against for best performance. Are you able to locally then remove the -march=native flag? The issue hasn't been encountered on the x86/ARM-based testing.
