Failure to build on powerpc64le

[daxtens]

Hi,

I'm getting a failure trying to install the gem on a powerpc64le system. The output of gem install rjb is:

Building native extensions.  This could take a while...
ERROR:  Error installing rjb:

It looks like sys/syteminfo.h isn't a header on powerpc, so that might be part of the reason. I'm not sure what you're trying to do with that header, but I'd be more than happy to help figure out what the powerpc equivalent would be.

Hi

Rjb should know the system architecture for loading JVM. And many system that does not define ARCH by its compiler, has sys/systeminfo.h. Therefore Rjb need that information. You have a chance to fix it, asking C people what macro is supplied by the compiler and what is the location of the jvm showing rjb/ext/load.c line.38 to 84, and create pull request.

Because I have no clue for powerpc linux, I must close this issue. Best regards.
