* No longer assume SDK toolchains are installed in /opt/poky
* [BUGFIX #568] where specifying paths to both the kernel and fs
  image caused an error due to POKY_NATIVE_SYSROOT never being
  set, triggering failure of poky-qemu-ifup/ifdown
* Cosmetic improvements to usage() functions by using basename

Hi Saul,

This commit needs to precede a merge of Josh's work to add a version directory to SDK toolchain installations. It eliminates all assumptions that toolchains are installed in /opt/poky and allows for arbitrary toolchain location locations.

It also fixes a bug I ran across when paths to both the kernel and filesystem image are specified, leading to POKY_NATIVE_SYSROOT not being set, which causes poky-qemu-ifup/ifdown to fail. [BUGFIX #568]

Hmm, you remove CROSSPATH yet still reference it later. I think the code
has become confused. I'm going to merge the patch as it improves the
situation compared to how it is at the moment. I'll give some background
though:

There are three things we really want to reference in PATH:

a) The "native" or "nativesdk" tools
b) The "cross" tools, i.e. TARGET_PREFIX-gcc
c) The "cross" tools without the prefix, e.g. "gcc", replacing the 
   usual gcc you'd find in PATH. This last part is to allow distcc in a 
   image to use the compiler outside the emulation.

The distcc thing did used to work but I doubt it does at the moment as I
think this has just been reduced to the native case accidentally.

The paths in the sysroot corresponding to these are:

/opt/poky/sysroots/HOST-pokysdk-linux/usr/bin
/opt/poky/sysroots/HOST-pokysdk-linux/usr/bin/TARGET-poky-linux
/opt/poky/sysroots/HOST-pokysdk-linux/usr/libexec/TARGET-poky-linux/gcc/TARGET-poky-linux/GCCVERSION/

and there are similar paths in a Poky build directory.

I hope that helps clear things up a bit.

Cheers,

Richard

Thanks Richard, that does clarify things. I will file a bug for this and 
address it soon.
