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
