Hi list,

I was very happy to see that Boost.Context has been fixed for PPC64. 
Thanks a lot for that. I was able to verify that the fix worked on the 
BlueGene/Q. Both on the Head node, which is a POWER7 and the compute 
nodes which are a PowerPC A2.

However, in order to build the library, I needed to manually call the 
assembler as the predefined commands did not work. For example, the BG/Q 
provided assembler doesn't know the "--64" switch and the assembler i 
want to use is called bgclang-as instead of plain as. For the compute 
nodes, I additionally want to use the -ma2 flag to  have the proper 
assembly generated.

Is there a way to have that configurable by the user? Right now, the 
only way i could find to fix that is to manually edit the Jamfile.v2 in 
the context build directory. Any advice or hints to fix it properly are 
highly appreciated.

Thanks,
Thomas
