#9398: get-invocation-command is not using user provided value in some cases
----------------------------+------------------------------
 Reporter:  nison.mael@…    |       Type:  Bugs
   Status:  new             |  Milestone:  To Be Determined
Component:  Building Boost  |    Version:  Boost 1.54.0
 Severity:  Problem         |   Keywords:
----------------------------+------------------------------
 Notably, the problem appears when trying to specify a custom <archiver> or
 <ranlib> option to either gcc or clang toolchains (the latter deriving
 from the former.

 The get-invocation-command rule executes a shell command then return the
 output, or the user provided value if the execution did not output
 anything.

 However, it means that the user cannot overwrite the tools paths and has
 to manually patch the toolset file to hardcode the tool path, which is an
 issue.

 The easy fix would be to check for an option before calling get-
 invocation-command (at least in gcc.jam, but it is possible that other
 toolsets are also affected). A maybe-not-so-easy-fix would be to change
 get-invocation-command behavior to return the user provided value if there
 is one, and to call the specified command if there is none (so the
 opposite of what is currently done).

 tl;dr : '''tools/build/v2/user-config.jam'''

 {{{
 using clang
 : 3.3
 : /home/arcanis/emscripten/emcc
 : <archiver>"/home/arcanis/emscripten/archiver"
   <ranlib>"/home/arcanis/emscripten/emranlib" ;
 }}}


 Doesn't (cannot) work
