Does your gst-plugin/src/Makefile.am have $(GST_BASE_LIBS) in
libgstmydemosrc_la_LIBADD , e.g.:

libgstmydemosrc_la_LIBADD = $(GST_LIBS) $(GST_BASE_LIBS)

?

What you can also do is to move the gstreamer-base-$GST_MAJORMINOR bit
into the

  PKG_CHECK_MODULES(GST, gstreamer-$GST_MAJORMINOR >= $GST_REQUIRED, ...

check, just add it after the gstreamer-$GST_MAJORMINOR >= $GST_REQUIRED
after a whitespace.
