Building libicu from
http://packages.ubuntu.com/hardy/libicu38
using
configure --build=i686-pc-linux-gnu --host=arm-3d-linux-gnueabi
make
Configured and built without issue for a while then blew up;

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make[1]: *** [rematch.o] Error 1
make[1]: Leaving directory `/tmp/icu/icu-3.8/icu/work/i18n'
make: *** [all-recursive] Error 2
Workaround:
Avoid using "-O2" on the compile line for the rematch.cpp source.
This can be done in the pre-configured source by patching;
icu-3.8/icu/source/i18n/Makefile.in
after the entry
"all-local: $(ALL_TARGETS)"
add
rematch.o: $(srcdir)/rematch.cpp
$(CXX) $(CPPFLAGS) $(DEFS) -c -o $@ $<
