embedding absolute path for shared libraries

Using a vendor provided cross-compiling toolchain (apparently an OpenEmbedded derivative), I'm unable to embed the absolute path to third-party (open source, compiled in house)libraries. With the following gcc command line:

arm-linux-gcc test_connect_send.o gprs_connect.o \
    /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libgprs_stuff.so \
    /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libpower_supply_stuff.so \
    /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libgsm_stuff.so \
    /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libtcp_stuff.so \
    /package/host/aspl.es/vortex-1.1.0/lib/libvortex-1.1.so \
    /package/host/aspl.es/axl-0.5.6/lib/libaxl.so.0  -o test_connect_send

objdump says:

Dynamic Section:
  NEEDED      /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libgprs_stuff.so
  NEEDED      /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libpower_supply_stuff.so
  NEEDED      /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libgsm_stuff.so
  NEEDED      /package/host/myvendor.com/API-R-2.0.0/Release/Libraries/libtcp_stuff.so
  NEEDED      libvortex-1.1.so.0
  NEEDED      libaxl.so.0
  NEEDED      libgcc_s.so.1
  NEEDED      libc.so.6

Notice how my vendor's libraries do have their full path, while aspl's don't. Also, notice how the name embedded is different from the one I specified on the command line. I'd like to know why (who is messing with my paths), and how to solve it.

p.s.: I know about RPATH, that's not the answer I'm looking for

My guess would be that the vendor supplied libs set the SONAME to the full installed path.
