Hi

Some of you may remember me from old times. Recently I got some work to
do related with OpenEmbedded but I need working toolchain on target device.

I use openembedded-core and got few problems with "core-image-lsb-sdk"
on qemux86 target (final image will be armv7 or even armv8 later).

First thing: binutils - "ld: this linker was not configured to use
sysroots" even with simple hello.c source. Fix attached.

Second thing: gcc (or rather g++) which is unable to find STL headers
(after installing libstdc++-dev package):

ignoring nonexistent directory "usr/include/c++/"
ignoring nonexistent directory "usr/include/c++//i586-oe-linux"
ignoring nonexistent directory "usr/include/c++//backward"
ignoring nonexistent directory "/usr/local/include"
ignoring nonexistent directory
"/usr/lib/gcc/i586-oe-linux/4.7.1/../../../../i586-oe-linux/include"

 /usr/lib/gcc/i586-oe-linux/4.7.1/include-fixed
 /usr/include
 ../lib/compat
End of search list.

So far I did not looked at fixing this part but will do as I want to be
able to build anything on target.

So what status is of C/C++ toolchain in OE-Core?
