build: add builds for windows, linux & darwin

- add bare and full featured builds for:
    - darwin/amd64
    - darwin/arm64
    - linux/i386
    - linux/amd64
    - linux/arm
    - linux/arm64
    - windows/i386
    - windows/amd64
    - windows/arm
    - windows/arm64
- update build steps to remove out dir before rebuild
- omit symbol table and debug information in final build
- omit DWARF symbol table
- replace the following variables in the source files with values:
    - VERSION: is replaced with the current version defined in the
      makefile, e.g.: 0.0.0-pre+1
    - BUILD_AT: is replaced with the date the build occured
    - BUILD_BY: is replaced with the 'user.name' and the 'user.email',
      both values are aquired using the 'git config --global' command
      and therefore depend on the currently building machine and its git
      user.
- the bare build now prints the above variables on start
- the full featured build prints these if invoked with '--version'
