6e0a904fd0 Fix test case to be valid ANSI C++. 
Don't require use of fixed C++ header files, so "../gcc/xgcc -B../gcc/" ought
to work for CXX.

broken in this test case.

f2f824ae57 * config/i386-linux.mt: delete ".sh" from genscripts argument 
(change made to genscripts on July 21...)

This is all it took for linux-native ld to build. It isn't necessarily useful,
particularly as gcc is still configured to pass -m486 and -dll-verbose, which
this ld doesn't parse...
