[oe] [meta-ruby] problems building Gem that contains C code

[Eduardo Silva]

Hi,

I am packaging a Ruby gem that also contains C code:

  http://github.com/msgpack/msgpack-ruby

but when building it raise many QA issues about linking to 64 bits version,
my target is "i586-poky-linux":

ERROR: QA Issue: Architecture did not match (3 to 62) on

would you please advice if some specific flag/setup is required to build
Ruby gems that contains C code ?

thanks,
