Supported architectures:
Cross-compiler toolchain build script
Possible target platforms are:
aarch64 ARM64
amd64 AMD64 (x86-64, x64)
arm32 ARM
ia32 IA-32 (x86, i386)
ia64 IA-64 (Itanium)
mips32 MIPS little-endian 32b
mips32eb MIPS big-endian 32b
mips64 MIPS little-endian 64b
ppc32 32-bit PowerPC
ppc64 64-bit PowerPC
sparc32 SPARC V8
sparc64 SPARC V9
lm32 LatticeMico32
The toolchain is installed into directory specified by the
CROSS_PREFIX environment variable. If the variable is not
defined, /usr/local/cross/ is used as default.
If '--install no' is present, the toolchain still uses the
CROSS_PREFIX as the target directory but the installation
copies the files into PKG/ subdirectory without affecting
the actual root file system. That is only useful if you do
not want to run the script under the super user.

Example 1: Build a cross-compiler for 32-bit PowerPC using 4 cores without installing:
./toolchain.py --arch ppc32 --install no --cores 4
Example 2: Build and install a cross-compiler for 32-bit ARM (default install directory is /usr/local/cross, specify another one by exporting CROSS_PREFIX environment variable), note that you need 'sudo' to install:
sudo ./toolchain.py --arch arm32 --install yes
