usage="Usage: $0 \$gcc_release
Here \$gcc_release is a major gcc release for which the gcc-\$gcc_release-source
package exists
The cross-gcc-buildall helper script automates the process of building the full
set for target architectures locally. It needs sbuild 0.64.3 or later installed
and a chroot for the target suite available.
For instance, you can build a specific gcc for a specific target like this:
TARGET_LIST=armhf PARALLEL=8 ./cross-gcc-buildall 4.9
which will generate a package called cross-gcc-4.9-armhf inside the
cross-gcc-packages-amd64 directory.
