'make cross' needs gcc-g++ ?!

[Sergei Organov <osv at Javad dot RU>]

Hello,

Don't know if it is a bug or feature, but 'make cross' doesn't work if
only gcc-core is installed. It needs gcc-g++ to be installed as
well. Well, I re-read crossgcc FAQ and didn't find references to
'cross' target for make. Is it just obsolete or it never was an intended
way to make cross compiler? 'make all' works fine, so I hope there is no
actual trouble here.

Example: 

$ mkdir tmp; cd tmp
$ tar -xzf ../archive/gcc-core-2.95.1.tar.gz
$ mkdir build; cd build
$ ../gcc-2.95.1/configure --target=ppc-eabi
...
Links are now set up to build a cross-compiler for powerpc-unknown-eabi
  from i686-pc-linux-gnu.
...
$ make cross
...
make[1]: *** No rule to make target `c++', needed by `native'.  Stop.
make[1]: Leaving directory `/home/osv/tmp/build/gcc'
make: *** [cross] Error 2
$ make cross LANGUAGES=c
...
Building the C and C++ compiler
make[1]: Entering directory `/home/osv/tmp/build/gcc'
(cd intl && make all)
make[2]: Entering directory `/home/osv/tmp/build/gcc/intl'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/home/osv/tmp/build/gcc/intl'
make[1]: *** No rule to make target `c++', needed by `native'.  Stop.
make[1]: Leaving directory `/home/osv/tmp/build/gcc'

Thanks,
