The 'external' toolchain file does nothing but transitively sets some cmake system variables from values received on the command line, and forcibly sets the C compiler. However, the same cmake system variables can be directly set via the command line, together with the C compiler, and specifying a toolchain is not a must. Thus, this patch drops the superfluous 'external' toolchain file and updates cmake-based targets to invoke cmake in a simpler form. Related changes in this commit: - While updating the cmake invocations, all the command line arguments have been reviewed and simplified (removed those, which did not change the defaults). - Removed unnecessary forced C compiler settings from some toolchain files (and/or changed them to setting the "compiler works" flag to true, thus keeping cmake's compiler identification logic but disabling some of its overzealous compiler sanity checks).
