Error during updating print/ghostscript9 to version 9.06_1

There is misprint in the last update of patch 'files/patch-base-gs.mak'.
http://www.freebsd.org/cgi/cvsweb.cgi/ports/print/ghostscript9/files/patch-base-gs.mak?rev=1.2

Output of $(GEN_CONF) is redirected to stdout for awk-script processing, but `$(gconfxx_h)` still not removed from parameters.

This misprint prevent generation of `gconfxx.h` header file and subsequent creation of `ld.tr` file.
