Bug #7653: Array.pack ignores Big Endian modifier
https://bugs.ruby-lang.org/issues/7653

Running on Linux, it seems that L> modifier is ignored:

irb(main):024:0> [2**16].pack('L<')
=> "\000\000\001\000"
irb(main):025:0> [2**16].pack('L>')
=> "\000\000\001\000"

Expected result:

irb(main):024:0> [2**16].pack('L<')
=> "\000\000\001\000"
irb(main):025:0> [2**16].pack('L>')
=> "\000\001\000\000"

I can't reproduce it on Ubuntu x86_64 with Ruby(mri) 1.9.3p125, what 
version of Linux are you using?
