+Without this patch, the command
+
+RUNTESTFLAGS=--target=powerpc-750-linux-gnu -v -v -v -v make check-target-libstdc++-v3
+
+fails in two ways:
+1. the -L option meant to locate the testsuite directory is incorrect, and
+2. the wrong compiler is invoked, causing all sorts of havoc, not least of which
+is the native compiler is invoked when we really wanted to invoke the cross-compiler
+we just built.
+
+Here's an example log of the problem in action.  Every testcase fails, this shows just one:
+-------------
+Invoking the compiler as g++ -ggdb3 -DDEBUG_ASSERT -I/home3/dank/wk/ixos/dap_interim/linux/3rdParty/crosstool/crosstool-0.12/build/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/gcc-3.3/libstdc++-v3/testsuite /home3/dank/wk/ixos/dap_interim/linux/3rdParty/crosstool/crosstool-0.12/build/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/gcc-3.3/libstdc++-v3/testsuite/20_util/binders.cc   -g -O2 -DDEBUG_ASSERT  -L/testsuite -lv3test -lm  -o ./binders.exe
+compiler exited with status 1

+FAIL: 20_util/binders.cc (test for excess errors)

+-------------
+
+And here's the patch.  I'm not happy with it, and it probably gets some cases wrong,
+but it seems to work for the common native case and for my cross-compiler case.
