Framewave

I had to apply the attached patch plus the following:

sed -i -e 's/-lpthread/-lboost_thread-mt/'
BuildTools/buildscripts/fwflags_gcc.py

to be able to compile against the system boost library. It would be nice
if this could be a build option.

Also, I end up with:

framewave.i386: W: unused-direct-shlib-dependency
/usr/lib/libfwImage.so.1.1.0 /usr/lib/libboost_thread-mt.so.3
framewave.i386: W: unused-direct-shlib-dependency
/usr/lib/libfwVideo.so.1.1.0 /usr/lib/libboost_thread-mt.so.3
framewave.i386: W: unused-direct-shlib-dependency
/usr/lib/libfwJPEG.so.1.1.0 /usr/lib/libboost_thread-mt.so.3
framewave.i386: W: unused-direct-shlib-dependency
/usr/lib/libfwSignal.so.1.1.0/usr/lib/libboost_thread-mt.so.3

because all of these get linked against libboost_thread-mt (or pthread
without the change) but don't need to be. LDFlags should be able to
different for different library targets.
