[bbv2] Unable to build .so on Solaris with g++

When trying to build a small shared library with BBV2 and gcc 3.3.4 on
Solaris and I get the error reproduced below.

The link command doesn't pass -dn or -P to the linker directly, but I
believe the mistaken -rpath-link flag is treated by Sun ld as a
bundled option which would enable both the "-a" and "-r" options which
are mutually exclusive:

-a In static mode only, produces an executable object
file; gives errors for undefined references. This is
the default behavior for static mode. -a may not be
used with the -r option.

-r Combines relocatable object files to produce one relo-
catable object file. ld will not complain about
unresolved references. This option cannot be used in
dynamic mode or with -a.

In gcc.jam there is the following comment:

# Solaris linker does not have a separate -rpath-link, but
# allows to use -L for the same purpose.
flags $(toolset).link LINKPATH $(condition) : <xdll-path> :
unchecked ;

But further down:

actions link.dll bind LIBRARIES
{
"$(CONFIG_COMMAND)" -L"$(LINKPATH)" -Wl,-R$(SPACE)-Wl,"$(RPATH)"
-o "$(<)" $(HAVE_SONAME)-Wl,-h$(SPACE)-Wl,$(<[1]:D=) -shared "$(>)" 
"$(LIBRARIES)" -l$(FINDLIBS-ST) -l$(FINDLIBS-SA) $(OPTIONS) 
}
