Configuring in p/rts fails when host!=build (for example when building native compiler for DJGPP or MINGW under Linux) as newly built xgcc and xgpc cannot be run on build system. In this case we should run corresponding cross-compiler instead.
Included patch is tested only for --build=i686-pc-linux-gnu, --host=i586-mingw32msvc --target=i586-mingw32msvc
