eclipse support: document script and add checks
As requested by Peter, add a bit of documentation in the eclipse-register-toolchain script, and add a few more checks (even though this script is not intended to be executed manually, which is also now mentionned in the documentation).

+# This script registers the toolchain of a Buildroot project into the
+# Eclipse plugin. To do so, it adds a new line for the Buildroot
+# toolchain into the $HOME/.buildroot-eclipse.toolchains file, which
+# the Eclipse Buildroot plugin reads to discover automatically the
+# available Buildroot toolchains on the system.
+# This script should typically not be called manually. Instead, one
+# should enable the BR2_ECLIPSE_REGISTER configuration option, which
+# will lead Buildroot to automatically call this script with the
+# appropriate arguments.
+# Usage:
+# eclipse-register-toolchain project-directory toolchain-prefix architecture
+# project-directory is the absolute path to the Buildroot project
+# output directory (which contains the host/, target/, build/,
+# images/, etc. subdirectories). It should be an absolute and
+# canonical path.
+# toolchain-prefix is the prefix of the cross-compilation tools, i.e
+# 'arm-linux-' if the cross-compiler executable is 'arm-linux-gcc'.
+# architecture is the lower-cased name of the architecture targetted
+# by the Buildroot project.
