[OE-core] tiff compile fails

[Andreas Müller]

With latest git pull for oe-core/meta-oe... & clean build dir I get

| arm-angstrom-linux-gnueabi-libtool: compile:  ccache arm-angstrom-linux-gnueabi-g++ -march=armv7-a -fno-tree-vectorize -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a8 -mthumb-interwork -mno-thumb --sysroot=/home/Superandy/tmp/oe-core-eglibc/sysroots/overo -DHAVE_CONFIG_H -I. -O2 -pipe -g -feliminate-unused-debug-types -fpermissive -fvisibility-inlines-hidden -fvisibility-inlines-hidden -MT tif_stream.lo -MD -MP -MF .deps/tif_stream.Tpo -c tif_stream.cxx  -fPIC -DPIC -o .libs/tif_stream.o
| tif_stream.cxx:31:20: fatal error: iostream: No such file or directory
| compilation terminated.
| make[2]: *** [tif_stream.lo] Error 1

I think it is not tiff to blame - but which one is it?
