On a closer look, it seems that the configure script ignored LDFLAGS.
Building a file with just plain make seems to make use of LDFLAGS:

$ make hi
c++ -O2 -fno-strict-aliasing -pipe  hi.cc  -o hi
$ rm hi

$ CXXLINK=apa make hi
c++ -O2 -fno-strict-aliasing -pipe  hi.cc  -o hi
$ rm hi

$ LDFLAGS=apa make hi
c++ -O2 -fno-strict-aliasing -pipe apa hi.cc  -o hi
c++: apa: No such file or directory
*** Error code 1

(As seen above, I also tried CXXLINK, but that wasn't used.)

So, if you feel like trying SVN revision 5617, then it should work as
long as your LDFLAGS contains -lgomp.
