I presume you know what this gcc/cflags=-fPIC syntax means? It means:
"in addition to any other variants", build everything with "toolset=gcc cflags=-fPIC".
So, the above builds 5 variants:

        gcc/variant=release,debug (2 variants here)
        gcc/cflags=-fPIC
        gcc/cxxflags=-fPIC
        gcc/linkflags=-fPIC

Do you want it? Try removing "gcc/" everywhere.
