Summary

0000129: 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.

Additional Information

My profile describes the host machine, but here it is again:
iBook G3 900 MHz
Gentoo Linux
kernel version 2.6.10-gentoo-r6
native gcc compiler version 3.4.1 20040803

Notes
(0000071) rlc 03-02-05 23:05	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.
