big-endian, 64-bit architectures:

# 2.4 History Variables

Use of uninitialized value in string eq at t/readline.t line 119.

Side-remark: It looks it only started failing on the last rebuild
round, up to 1.34-1+b1 all builds were fine.

The failing test is 

#   Failed test 'readline_state'
#   at t/readline.t line 152.

where the observed value is 0 instead of the expected 2.

The problem here is that with readline-7.0, rl_readline_state has changed
from int to unsigned long. The int_tbl[] initialization in Gnu.xs coerces
this to an int in a way that works on little-endian 64-bit platforms
but not big-endian ones.

I'm not sure how to best fix this. The attached crude hack makes it work,
but I hesitate call it a patch. I've forwarded it upstream FWIW.
