[Llvm-bgq-discuss] clang on BGQ performance

edited Makefile to skip the fortran and set bgclang vars

bbpbgas040:~/bgas/clang/build/stream$ cat Makefile

CC = bgclang
CFLAGS = -O3 -fopenmp -L/gpfs/bbp.cscs.ch/home/biddisco/apps/clang/bgclang/omp/lib/

all:  stream_c.exe

stream_c.exe: stream.c
        $(CC) $(CFLAGS) stream.c -o stream_c.exe

clean:
        rm -f stream_c.exe *.o


then just a make. I didn't set any other vars (like TUNED etc)
