coreutils-8.26: build workaround for Bitrig 1.0

[Nelson H. F. Beebe]

A build of coreutils-8.26 failed on Bitrig 1.0 (an OpenBSD relative)
because of this error:

        CCLD     src/libstdbuf.so
        /usr/bin/ld: /usr/local/lib/libintl.a(dcigettext.o): relocation 
            R_X86_64_32 can not be used when making a shared object; 
            recompile with -fPIC 
            /usr/local/lib/libintl.a: could not read symbols: Bad value

The configure-generated LDFLAGS and other Makefile variables supplies
libintl.a and libiconv.a, static libraries, yet those settings are
then used incorrectly to link a shared object.

The solution was to replace the two .a file mentions in all Makefiles
with their corresponding .so.* files; the builds then completed, and
only a single test failed:

        FAIL: tests/mv/i-3.sh

I installed the patched build.
