Looks like ar from devel/binutils is broken on your machine.  On my most
recently updated machine:

%ldd /usr/local/bin/ar
/usr/local/bin/ar:
	libfl.so.2 => /usr/local/lib/compat/pkg/libfl.so.2 (0x8810d000)
	libm.so.5 => /lib/libm.so.5 (0x8810f000)
	libz.so.6 => /lib/libz.so.6 (0x88137000)
	libc.so.7 => /lib/libc.so.7 (0x8814c000)

That doesn't look good ...

At first I suspected that libfl.so might have had a version bump, but
there's no other shard library version under /usr/local/lib.  There is a
static library, libfl.a, installed by textproc/flex.  It turns out that
installation of shared libraries was disabled for that port by r345345
two weeks ago (PR: ports/186790).  There should have been a note in
ports/UPDATING notifying users to rebuild or reinstall all ports that
linked to the shared library.

What's interesting is that devel/binutils doesn't mention flex as a
dependency.

In any case, rebuilding and reinstalling devel/binutils should get you
to the point where you can build lang/gcc47.
