Subject: detect 64bit processors and add -fPIC
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=mussa.git;a=commitdiff_plain;h=974e1b5bb6822a96aac25f5e35d1405b0c36b279

detect 64bit processors and add -fPIC
this is an intermediate solution as I probably can use ADD_DEFINES()
to add the command line options for the compiler instead of fiddingly
with CMAKE variables

Props to Brandon for finding the solution in an openwengo patch.
