[Buildroot] ICU 51.2 bus error

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

Jumping back to this old topic while trying to clean up some of my
"marked" e-mails.

Vicente, the below is a bug report of a runtime issue regarding ICU on
MIPS. Can you have a look maybe?

Thanks!

Thomas
