   cross-compile support for SCons

   scons build system searches paths for hard-coded tool names like "gcc",
   so this patch teaches it to check first for a tool with cross-compile
prefix
   if the CROSS_COMPILE variable has been set. If not found, it falls back
   to searching for the un-prefixed tool name.

   For example, if CROSS_COMPILE=arm-angstrom-**linux-gnueabi-
   SCons.Evironment.Detect('gcc') should find arm-angstrom-linux-gnueabi-gcc
   SCons.Evironment.Detect('zip') should find plain zip

Shouldn't these go to the oe-core list?

    cross-compile support for SCons
    
    scons build system searches paths for hard-coded tool names like "gcc",
    so this patch teaches it to check first for a tool with cross-compile prefix
    if the CROSS_COMPILE variable has been set. If not found, it falls back
    to searching for the un-prefixed tool name.
    
    For example, if CROSS_COMPILE=arm-angstrom-linux-gnueabi-
    SCons.Evironment.Detect('gcc') should find arm-angstrom-linux-gnueabi-gcc
    SCons.Evironment.Detect('zip') should find plain zip
