 From looking at svn logs,

"libOPCODE_a_CPPFLAGS= -O2 -fno-strict-aliasing -fPIC"  is my mistake. I 
added it in r906 while trying to get ODE to compile on x86_64 and I 
forgot to remove it in r907 when adding the conditional "if 
X86_64_SYSTEM [...]".

-fPIC was not present before r906/r907 and thus would not compile on 
x86_64. I must admit that I do not know the -fPIC option very well, 
hence I added it only to fix the compilation on x86_64 (since regular 
x86 was already working), not knowing its implications on other platforms.
