Using SOCKS 4/5 proxy is no easy task:
- a machine may well be able to reach the proxy, even if it is not on the same sub-net(s) as the machine itself (absolutely legitimate)
- tsocks.conf needs a list of so-called 'local' networks that can be reached without the need for a SOCKS connection
- SOCKS proxies are expected to be in 'local' networks
- there is absolutely NO way to tell what networks are local, besides the sub-net(s) the machine is in

Therefore, appropriate configuration of SOCKS 4/5 configuration is really complex, and attempts to correctly overcome this issue are doomed.

     3 RUNTESTFLAGS=--target=powerpc-750-linux-gnu -v -v -v -v make check-target-libstdc++-v3

     4 

     5 fails in two ways:

     6 1. the -L option meant to locate the testsuite directory is incorrect, and

     7 2. the wrong compiler is invoked, causing all sorts of havoc, not least of which

     8 is the native compiler is invoked when we really wanted to invoke the cross-compiler

     9 we just built.

    10 

    11 Here's an example log of the problem in action.  Every testcase fails, this shows just one:

    12 -------------

    13 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

    14 compiler exited with status 1

    15 output is:

    23 WARNING: 20_util/binders.cc compilation failed to produce executable

    24 -------------

    25 

    26 And here's the patch.  I'm not happy with it, and it probably gets some cases wrong,

    27 but it seems to work for the common native case and for my cross-compiler case.
