Tom, Khem,
This change seems to break external-toolchains, e.g. CodeSourcery Lite, at
least 2009q1 (gcc-4.3 based)...
I'm seeing issues like this in libxau:
| ./include/X11/Xauth.h:48:31: error: X11/Xfuncproto.h: No such file or directory
| ./include/X11/Xauth.h:49:27: error: X11/Xfuncs.h: No such file or directory
It cannot find standard X headers from OE sysroot.
Do I need to pass an extra --sysroot to CSL? Any other pointers?
Here's (hopefully useful) info from my toolchain:
$ arm-none-linux-gnueabi-gcc -print-sysroot
