    Bow out gracefully if amu_machine environment variable unset · 8b7e5a78

    srcbuild looks up the name of the make tool to use from an environment
    variable ("Alias$amu_machine" on RISC OS, "AMUMACHINE" otherwise). However,
    there was no error handler for the case where the variable was unset.
    (This explains the segfaults experienced when cross-compiling older source
    trees.)
