icu: fix usage of libicudata on ARM EABIhf

Browse Source 
The libicudata library was linked as a "data only" library using the
-nostdlib -nodefaultlibs flags, but this causes problems when using
the library on ARM EABIhf systems. Removing those flags fixes the
problem, and is the solution used by Debian, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653457 for all the
details.

[Thomas: fix commit log and title, add more details to the patch
description.]

Subject: [PATCH] Don't link icudata as a data only library
This patch cames straight from Debian. It fixes an issue when
libicudata would not have some flags indicating it's EABIhf, causing
applications linked against libicudata to not start on EABIhf
systems. Getting rid of the -nodefaultlibs -nostdlib flags solves the
problem, and is the solution that is used by Debian, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653457.
