-Don't build object files twice
-
-When passed --enable-static and --enable-shared, icu will generate
-both a shared and a static version of its libraries.
-
-However, in order to do so, it builds each and every object file
-twice: once with -fPIC (for the shared library), and once without
--fPIC (for the static library). While admittedly building -fPIC for a
-static library generates a slightly suboptimal code, this is what all
-the autotools-based project are doing. They build each object file
-once, and they use it for both the static and shared libraries.
-
-icu builds the object files for the shared library as .o files, and
-the object files for static library as .ao files. By simply changing
-the suffix of object files used for static libraries to ".o", we tell
-icu to use the ones built for the shared library (i.e, with -fPIC),
-and avoid the double build of icu.
-
-On a fast build server, this brings the target icu build from
-3m41.302s down to 1m43.926s (approximate numbers: some other builds
-are running on the system at the same time).
