This is required for the tests.

Haiku comes currently in 2 different flavour: 32 and 64 bit.
64 bit have only one toolchain, so it is easy, but 32 bit comes with 2 different (GCC2 primary and GCC7 secondary). Ruby built with GCC7 on Haiku, so it needs to pick the secondary arch libroot.so.
libroot.so is a complex lib which provides the libm and libc functionality, and probably much more.

Could you please make a pull-request for ruby/fiddle repository?

Off topic a little, I think this code is wrong.

  case [0].pack('L!').size
  when 4
    # 32-bit ruby
  when 8
    # 64-bit ruby
  end

This selects the platform by the size of long, but it may differ from the address bus size, e.g., mswin/mingw.
The size should be [0].pack('J').size (2.3 or later) or [""].pack('p').size,
or, much better, RbConfig::CONFIG['void*'].
