Workaround toolchain bugs

​

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.qq
