Add possibility to add project specific toolchains

[ReneW10]

Let's say there is a project with a specific toolchain.
Can it be added to bake by adding a path to toolchain description via command line?

E.g. the toolchain description is located under C:\projs\myProj\etc\bake\ with toolchain and error parser description specificToolchain.rb and specificToolchainErrorParser.rb.
And
bake --add-toolchains C:\projs\myProj\etc\bake\ --toolchain-names
would list the normal toolchains, plus the specificToolchain.

Thank you for the idea. I would like to do that, but that is not easy.
Adding the compiler flags + error parser is one thing, but every compiler front-end has different handling, e.g. how to generate dependency files, pointing to the linker script(s), etc. So maybe I have to provide a more generic mechanism how to call the compiler/archiver/linker.
I leave this ticket open as a reminder to think about it more deeply in future.

Until this is done, feel free to send me your new compiler (settings). You could simply try them out by changing the bake-toolkit ruby code (where ruby is installed). You could manipulate an exisiting compiler to reduce the effort. Example for gcc if you have Windows and ruby 2.0.0 installed at C:\tools\ruby200 with bake-toolkit 2.34.4:

C:\tools\ruby200\lib\ruby\gems\2.0.0\gems\bake-toolkit-2.34.4\lib\bake\toolchain\XY.rb
C:\tools\ruby200\lib\ruby\gems\2.0.0\gems\bake-toolkit-2.34.4\lib\bake\toolchain\errorparser\XY_compiler_error_parser.rb
C:\tools\ruby200\lib\ruby\gems\2.0.0\gems\bake-toolkit-2.34.4\lib\bake\toolchain\errorparser\XY_linker_error_parser.rb

Any news on this? We're in a situation where this would be quite handy, since we don't want to change the global bake installation on Jenkins.
