I am building Boost.Log on a relatively new machine whose compiler and 
CPU both support the AVX2 instruction set. Boost.Log detects this at 
build time and configures its compiler flags accordingly to use the AVX2 
instruction set. I'd like to use the resulting binaries, however, on 
older systems that do not have AVX2 support. Is it possible to 
explicitly disable this at build time? I didn't see any mention of it in 
the documentation, and my attempts to parse the Jamfile's intentions 
were not successful.

Thank you.
