icu: workaround toolchain bugs

Browse Source 
Many of ARM Sourcery CodeBench toolchain have a bug when compiling
icu's translit.cpp source file. The bug is trigerred when there is a
combination of "-W -Wall" and "-Os", and causes an internal compiler
error. The bug has been reported to Mentor Graphics.

Even though it is clearly a toolchain bug, having a workaround for it
is trivial in this case. So it will avoid our users falling into this
internal compiler error, and allow our autobuilders to test more
packages using this Sourcery CodeBench toolchain.
