[boost] Parts of linkflags are disappearing: $ISALIST gone

My linkflags setting involves a dollar sign:

linkflags='-R/opt/csw/lib/$ISALIST'

The $ISALIST dynamic token tells the linker to iterate through
supported instruction sets and pick the best one[1].

When the Boost binaries are built, the RPATH in the binaries is
missing the dollar sign and everything after it:

$ /usr/ccs/bin/dump -Lv
work/solaris10-sparc/pkgroot/opt/csw/gxx/lib/sparcv9/libboost_iostreams.so.1.49.0
| grep RPATH
[13]    RPATH
/opt/csw/lib/64:/opt/csw/gxx/lib/:/opt/csw/gxx/lib/64:/opt/csw/lib/

Do you see the /opt/csw/lib/ bit with the slash at the end? It could
be explained by the contents of linkflags being interpolated by a
shell. In my build, it's important to pass the dollar sign unchanged.
Here's an example of correctly set RPATH:

/usr/ccs/bin/dump -Lv /opt/csw/lib/libz.so.1 | grep RPATH
[6]     RPATH           /opt/csw/lib/$ISALIST:/opt/csw/lib

I need to pass the same flag to Boost libraries. Has anyone else seen
this problem?
