Build src/common files as a library with -fPIC.
Build a third version of libpgcommon.a, with -fPIC and -DFRONTEND, as commit ea53100d5 did for src/port. Use that in libpq to avoid symlinking+rebuilding source files retail. Also adjust ecpg to use the new src/port and src/common libraries. Arrange to install these libraries, too, to simplify out-of-tree builds of shared libraries that need any of these modules.
