First, thank you for using B2 :-) Second, we're going to need a bit more info to help you out. Can you tell us what version of B2 you are using? Do you have a minimal sample project that replicates the issue? What's in your config files? Can you provide that custom toolset? etc.
What I am trying (and miserably failing) to do is add the -Wl,--start-group
flag /before/ all the libraries I just compiled for my project are given to
the linker. For example, if I use the <link-flags> property, boost.build
will give me this kind of output:
<my-linker-executable> -o <output-location> <list-of-all-my-libs>
-Wl,--start-group <other-linked-libs> <rest-of-link-flags> ....and so on.

Indeed.
