Static library naming error for static libs #377

For static compilation i should get i.e.:

libboost_thread-vc143-mt-sgd-x64-1_80.lib

but i get:

libboost_thread-vc143-mt-gd-x64-1_80.lib

when using b2.

's' forgotten for -sgd-.

Error: fatal error LNK1104: cannot open file 'libboost_thread-vc143-mt-sgd-x64-1_80.lib'
