On my box w/ jre7-openjdk-headless 7.u40_2.4.1-1 installed, $JAVA_HOME pointing to /usr/lib/jvm/java-7-openjdk, and /usr/bin/java a symlink to
/usr/lib/jvm/java-7-openjdk/jre/bin/java
running jruby anything (e.g. jruby -v) gives the following warning:
"OpenJDK 64-Bit Server VM warning: You have loaded library /opt/jruby/lib/native/arm-Linux/libjffi-1.2.so which might ha
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'."

I notice in the PKGBUILD it clears out directories for other architectures from /opt/jruby/lib/native/, but I still have arm-Linux/, i386-Linux/, include/, and x86_64-Linux/ in there (I'm on x86-64). I was thinking one think that could be done, would be not make the arch=(any), but rather 32 | 64 bit, and use information about the current arch to further prune jruby/lib/native/ ? Or is this something maybe best left to the end-user - they can prune those extra native libs after they install the package to get rid of that warning?
