Gcc compiler is not part of Solaris 8. You can use LD_LIBRARY_PATH in
runtime or LDFLAGS for ./configure setup. I guess, that your suggested
patch could be generate unexpected result for other people.

By the way, sun studio compiler is significantly better on SPARC cpu
than  gcc. You can download it from sun webpage. Also if you can upgrade
OS than Solaris 10 is faster and you can use DTrace probes in postgres.
