cross-gcc --version
cross-gdb --version
cross-ar --version
ls -l output/staging/lib*/libc-*.so

  Kernel version is a bit more difficult: cat 
output/staging/usr/include/linux/version.h and convert the decimal 
version number to hex.

  Look at the rest of the toolchain-external/Config.in for examples.

  The supported architectures should also be mentioned, but that may be 
more difficult.

  Yes, only the latest one.

  We do usually keep an older version around as well, but I'm not really 
sure why. For the Sourcery toolchains it makes sense because they have 
different gcc versions, but the Linaro toolchains often only have 
bugfixes between one version and the next.
