Quoting from the linked mail,

"""
  Combining static libs into a shared lib is not really portable, you have to
  take care that you use the correct linker flags for the libs so that it will
  work.
"""

This is the reason I wouldn't consider the "link all the static libs
into a shared lib" approach.  For instance, on x86_64/gcc you need to
compile any files which will eventually become shared objects with the
-fPIC flag, but this doesn't happen automatically when creating static
libs.

AFAIK the flag isn't necessary on x86, and it may be something
different again on other platforms, hence the "not really portable"
comment I suppose.
