Adjusted for gcc-3.3-20040119

See http://gcc.gnu.org/PR12010

Without this patch, one gets both compile and link time errors in
'make check' when configured for cross-compiling.

In particular, 'make check' on a cross-compiler fails with

/testsuite_flags: /testsuite_flags: No such file or directory
    while executing
"exec sh ${odir_v3}/testsuite_flags --build-includes"
    (procedure "g++_include_flags" line 21)
    invoked from within
"g++_include_flags [get_multilibs] "
    (procedure "g++_init" line 63)
    invoked from within
"${tool}_init $test_file_name"
    (procedure "runtest" line 19)
...
make[1]: [check-g++] Error 1 (ignored)
