[Boost-build] [1.35] Weird behavior while building bjam under linuxx86_64 platform.

Hi, all

I've posted this weird problem in boost.user mailing list, but seems no 
one is interested in it. Also, boost.jam list seems not so helpful. So 
I'm trying my luck here :-)

I'm trying to build boost 1.35 within a RedHat x86-84 box. The gcc 
version information is here:

   $ gcc -v
   Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.5/specs
   Configured with: ../configure --prefix=/usr --mandir=/usr/share/man 
--infodir=/usr/share/info --enable-shared --enable-threads=posix 
--disable-checking --with-system-zlib --enable-__cxa_atexit 
--disable-libunwind-exceptions --enable-java-awt=gtk 
--host=x86_64-redhat-linux
   Thread model: posix
   gcc version 3.4.5 20051201 (Red Hat 3.4.5-2)

   $gcc --version
   gcc (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)

While building bjam by invoking $BOOST_ROOT/tools/jam/build_dist.sh, I 
got error messages as following:

   ./bootstrap/jam0 -f build.jam --toolset=gcc --toolset-root= clean
   ...found 1 target...
   ...updating 1 target...
   ...updated 1 target...
   ./bootstrap/jam0 -f build.jam --toolset=gcc --toolset-root=

You see, the bin directory name is ":bin.linuxx86_64" rather than 
"bin.linuxx86_64". Weird? I've build boost 1.35 successfully under 
cygwin, and the bin directory name is exactly "bin.cygwinx86".

I think it is this wrong directory name that causes following linkage 
errors. Is it a bug or I missed something obvious in the documentation?

Any suggestion is appreciated!
