valid values for target?

[Birchmier, Masaki]

Hi,
I recently installed a hpux to  powerpc cross compiler  where I set the value of 
--target=powerpc-*-linux-gnu*
When testing the installation, I discovered the loader doesn't like  * in the path.

So I tried reinstalling everything with --target=powerpc-linux-gnu
binutils went ok, but gcc make failed with 

/home/gnu/gcc/gcc-2.95.2/libio/libio.h:30: -G_config.h: No such file or directory
make[1]: *** [iogetline.o] Error 1
make[1]: Leaving directory '/home/gnu/gcc/gcc-2.95-build2-powerpc/powerpc-linux-gnu/libio'
make: *** [all-target-libio] Error 2

I also noticed that this time configure  ran with mt-frag, the first installation did not.

What's the syntax for valid values for --target ?
Could you provide any suggestions for my make failure?
It didn't have any problems with -G_config.h  the first time through?

Thanks, 
Masaki
