Embedding the absolute path for shared libraries

Using a provider that provides cross-compilation of the toolchain (apparently a derivative of OpenEmbedded), I cannot insert the absolute path into third-party (open source compiled in home) libraries. In 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

Please note that my development libraries have a full path, but aspl does not. Also note how the embedded name differs from the name specified on the command line. I would like to know why (who is messing with my ways) and how to solve it.

ps: I know about RPATH, this is not the answer I'm looking for
