[Boost-build] Why are config checks being done with shared link when I configure static?

I'm getting really frustrated with these run_simple  configuration checks!
I've invested way too much time trying to get this to work with VxWorks.

A simple change to Jamfile.v2
(yes I know it's a generated file)

import testing ;

actions simple_run_action
{
    $(LAUNCHER)  $(>) > $(<)
}

And now I can execute the test on the target system

. ./vxworks_env.sh &&  cd status   &&  \
                                BOOST_TELNET_ADDR="dummy"  \
                                LAYER_SRC_PATH="yow-build40-lx:VSB_Sim32/3pp/BOOST/boost_1_59_0" \
                                PKG_SRC_BUILD_DIR="/yow-build40-lx1/bkuhl/workspace/VSB_Sim32/3pp/BOOST/boost_1_59_0"  \
                                VSB_LD_LIBRARY_PATH="yow-build40-lx:VSB_Sim32/usr/root/gnu/bin;yow-build40-lx:VSB_Sim32/usr/lib/common" \
nice ../b2 -j6 --prefix=/yow-build40-lx1/bkuhl/workspace/VSB_Sim32/usr/root --libdir=/yow-build40-lx1/bkuhl/workspace/VSB_Sim32/usr/lib/common --includedir=/yow-build40-lx1/bkuhl/workspace/VSB_Sim32/usr/h/public    link=static toolset=gcc cross-compile=vxworks  "testing.launcher=./vxworks_boost_test_run.exp" "--limit-tests=atomic|context"  -q  -d2

So why do they all fail ?

Oh look!
It's doing a shared link when I asked for link=static  libraries?

  [vxWorks *]# ../bin.v2/libs/config/checks/gcc-4.8.1/debug/target-os-vxworks/cxx11_variadic_macros_exe
Launching process '../bin.v2/libs/config/checks/gcc-4.8.1/debug/target-os-vxworks/cxx11_variadic_macros_exe' ...
Process '../bin.v2/libs/config/checks/gcc-4.8.1/debug/target-os-vxworks/cxx11_variadic_macros_exe' (process Id = 0x884b80d0) launched.
Shared object "libunix.so.1" not found

OK, try  link-runtime=static typically make no difference, but I'll try it anyway.
... try that, ... first  I have to delete  bin.v2/project-cache.jam
Try again....
Nope, sigh
