The libstdbuf shared lib was restricted to gcc elf systems,
due to the amazing variance for shared lib support on various systems.
I didn't want to introduce libtool either due to the added complexity.

So...

If you look in src/Makefile.am you can see:

  # Note libstdbuf is only compiled if GCC is available
  # (as per the check in configure.ac), so these flags should be available.
  # libtool is probably required to relax this dependency.
  libstdbuf_so_LDFLAGS = -shared
  libstdbuf_so_CFLAGS = -fPIC $(AM_CFLAGS)

So I guess you might need to tweak those options?
If you get it working it would be great if you
could report back so that we might support something
more generic in the build.
