Thanks.

That seems to cause havoc on x86_64

/usr/bin/ld: error: /home/hunold/src/devel/boost/bin.v2/libs/math/build/clang-
linux-2.9/debug/sph_neumannf.o: requires unsupported dynamic reloc; recompile 
with -fPIC
clang: error: linker command failed with exit code 1 (use -v to see 
invocation)

Seem the compile commands are now missing -fPIC. I think -fPIC should be 
always added, as it is already done for gcc.jam. See the ML archives for 
details and rationale

It would be nice if you could clean up clang-linux.jam after all issue have 
been ironed out. Those commented out blocks are, well, annoying.

Yours,

Jürgen
