This is my working build section for 1.2.2, so not sure if it works
well with 0.10:

%Build
lt_cv_path_NM=nm \
./configure --prefix=%{_prefix} --host=$CFGHOST \
   --build=%{_build} \
   --disable-speex \
   --disable-shout2 \
   --disable-dv1394 \
   --disable-libdv --disable-libcaca \
   --disable-flac \
   --disable-cairo --disable-aalib \
   --disable-aalibtest  \
   --with-sysroot=${DEV_IMAGE}
perl -pi -e 's,^sys_lib_search_path_spec=.*,sys_lib_search_path_spec=,' libtool
make


I don't recall why I put the perl snippet in there.  My commit note
was "Beating the gst-* packages into submission so they build
correctly."

I usually poke around other BSP packages to see what they've done.
buildroot uses gst 0.10, yocto is on recent versions.
