[Boost-build] Passing <cxxflags>-fPIC with use-project /boost

Hello everybody,

I have a Jamroot that looks like this:

project 	:	requirements
                        <threading>multi
                        <toolkit>gcc,<address-model>64:<cxxflags>-fPIC
        :	build-dir stage
        :	default-build release
;

use-project /boost	: dependencies/boost_1_39_0 ;
use-project /test	: test ;

and a Jamfile located in test subdirectory that looks like this:

lib test 	:	[ glob-tree *.cpp ] 
                /boost//thread/<link>static 
                /boost//date_time/<link>static 
;

Now, to get the static linking to /boost//thread and date_time working I need to pass -fPIC when building with GCC on 64 bit platforms.

I can see that my own targets in lib sfcg gets compiled with -fPIC, but for some reason the /boost//thread and date_time libraries does not seem to "notice" it.

Everything will work perfectly if I pass cxxflags=-fPIC as a parameter to bjam on the command line. But I would prefer to cram as many details as possible into the Jamfiles, so I don't have to remember them later on ;-).

Any help would be greatly appreciated.
