I sounds like the makefile should be updated to handle the different
built variants.

1. Not all operating systems support internal library versioning. And
when they do, you still need a version number on the filename to allow
multiple versions of the same library to coexist.

2. Some developers, most Boost developers, have many compilers installed
so the toolset tag is needed so we can work with them all without

It depends on what the makefile wants. Looking at that makefile I see
that it uses both debug and release variants, so you need both of those.
And looking at the libs/regex/build/gcc.mak would suggest that only the
single-threaded variants are use.
