<CRITICAL> COFF IS BROKEN FOR NON-NATIVE CROSS-COMPILERS
The installer is only created if GCC built successfully

|BUILD|
[cross-canadian.sh]
* All instances of replacing the program prefix for building newlib and the
  build version of the target compiler use the target architecture
[build-coff.sh | build-elf.sh]
* Before attempting to create the installer, the build status is checked
[extract-source.sh]
* All additional libraries (MPFR, MPC, and GMP) are always copied to the GCC
  source directory
