    add preliminary aarch64 (arm64) support
dfaf77
    
dfaf77
    There has been some work to build fedora 19 on 64-bit arm armv8 machines
dfaf77
    (aarch64).  I took a look that the why the papi build was failing.  The
dfaf77
    attached is a set of minimal patches to get papi to build.  The patch is
dfaf77
    just a step toward getting aarch64 support for papi. Things are not all
dfaf77
    there for papi to work in that environment.  Still need libpfm to
dfaf77
    support aarch64 and papi_events.csv describing mappings to machine
dfaf77
    specific events.
