icu: fix usage of libicudata on ARM EABIhf

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.
