  So the link command ran by libtool is:

/opt/buildroot/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc -shared  -fPIC -DPIC

  (Just to be sure, could you go to the gobject directory and run the
above command to verify that it fails in the same way?  And also add the
-v option to it, so we can see how exactly gcc calls ld.)

  There are two strange things with this:

1. There is no mention at all of /lib or /usr/lib so why is ld looking
for pthread in those paths?

2. libtool adds -L/usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/usr/lib
-- where does that come from?

  Maybe there's something fishy in your environment.  Can you run
env | grep /lib
