[bug] QNX RANLIB not executed for built libraries

[Johnnyxy]

hi there,
I was trying to build boost (static libs) with QNX SDP 7.0 (compiler QCC 5.4.0).
As I noticed that the built static libraries do not have an index. This is because there is no following ranlib execution after library creation.

The problem here is that QNX has different RANLIB executables for different target architectures.
This means that the boost recipe cannot (easily) detect the correct executable it has to execute to create an index in the libraries.

As I have to specify the architecture in a pre-boost-build-step anyway (by setting environment variable RANLIB) I was looking for a way to modify the ranlib executable boost executes. In the GCC recipe I found out that it retrieves the executable from the <ranlib> feature (see here) what in turn gets set by the configuration (user-config.jam in my case). This file gets generated by a pre-boost-build-step and uses the data from the RANLIB environment variable. So I modifed the qcc.jam to support the same.

The result is that the qcc toolset retrieves the <ranlib> feature from the configuration.

See the patch file here:
boost_build_qcc_use_ranlib_feature.patch.txt

The problem with this approach is that it forces the user to specify a ranlib feature. But this could be undesireable. I tried to make it optional but had no success so far as I am no BJAM/JAM expert at all.
Can some BJAM-enthusiast help me out?
