Re: [Boost-build] Issues with Unix Linking -- Want to modify build command for custom toolchain

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.

That is rather strange. Since from what I can tell B2 should already be
putting the `-Wl,--start-group` at the front of all libraries (both built
and externally searched) <
https://github.com/boostorg/build/blob/develop/src/tools/gcc.jam#L1094>

What I am trying to do is this:

Indeed.
