There is already "CMAKE_SHARED_LINKER_FLAGS", though it is not
per-language.  Note that CMAKE_SHARED_LIBRARY_C_FLAGS was never
documented a s publicly settable variable AFAIK.  There is no
first-class interface to set per-language, per-target-type flags.
We could consider adding one, but that is a separate change.

I'll respond elsewhere in the original thread with a review of
the PIC topic.
