The difference is -R/opt/csw/lib which includes the runpath in the binary.
You can check with
  dump -Lv <binary>
e.g.

dam at unstable10s [unstable10s]:/home/dam/mgar/pkg/apache24/trunk > dump -Lv /opt/csw/bin/gcc

/opt/csw/bin/gcc:

  **** DYNAMIC SECTION INFORMATION ****
.dynamic:
[INDEX] Tag         Value

[3]     NEEDED          libm.so.2
[4]     NEEDED          librt.so.1

[9]     RPATH           /opt/csw/lib/$ISALIST:/opt/csw/lib:/opt/csw/lib
[10]    HASH            0x11094

For testing you can directly insert the runpath in the linker by setting
  export LD_OPTIONS=/opt/csw/lib
But beware! This insert the runpath before any other path set during build.
