Summary:                    Make menuconfig toolchain option "Additional gcc
options" passed into wrong build phase
Description: 
My embedded linux target requires the -mcpu=860 option to be passed into
the compilation phase of the GCC cross-compiler (if I don't, nothing
compiled with gcc will work!  It attempts to use non-existent
floating-point registers).  I put this option into the "Additional gcc
options" section of make menuconfig, but it attempted to use this as a
configure script option instead.  Here's the output:

configure: error: -mcpu=860: invalid option; use --help to show usage
make: ***
[/home/powerpc-linux/host/build/working/buildroot/toolchain_build_powerpc_nofpu/gcc-3.4.2-initial/.configured]
Error 1

If this is the intended use for this toolchain option, please tell me how
I can build gcc with the -mcpu=860 option.

I found the correct configure option:
--with-cpu=860

I believe this causes the cross-compiler version of gcc to assume
-mcpu=860

I was confused about where this option would be used, perhaps a more
descriptive name or help information could be added?
Please reduce the severity to trivial, my mistake.
