extend the rules/c-objs macro to take the way as a parameter
Previously we only built library package "cbits" the vanilla way, afterall
C code does not need to be built differently for profiling builds. However
for dynamic libs the C code needs to be built with -fPIC, so we do need
to be able to build package .c (and .s?) files multiple ways.
