i386: punt all config options that just control -march
You can set these yourself in your CFLAGS, and our list is incomplete and pointless (we agreed some time ago to stop doing this). We keep around CONFIG_[3456]86 because it is used to select between different optimized subdirs of handcoded assembly. Also take this opportunity to up the default to i686. If you're using an older cpu, then you can handle changing this yourself. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

This is the processor type of your CPU. This information is used for
- optimizing purposes. To build a library that will run on all x86 CPU
- types (albeit not optimally fast), you can specify "386" here. If
- you pick anything other than "386", there is no guarantee that uClibc
- will even run on anything other than the selected processor type.
-
- Here are the settings recommended for greatest speed:
- - "Generic 386" select this if your compiler is already setup to
- optimize things properly.
- - "386" for the AMD/Cyrix/Intel 386DX/DXL/SL/SLC/SX, Cyrix/TI
- 486DLC/DLC2, UMC 486SX-S and NexGen Nx586. Only "386" kernels
- will run on a 386 class machine.
- - "486" for the AMD/Cyrix/IBM/Intel 486DX/DX2/DX4 or
- SL/SLC/SLC2/SLC3/SX/SX2 and UMC U5D or U5S.
- - "586" for Intel Pentium and other generic Pentium CPUs
- - "Pentium-MMX" for the Intel Pentium MMX.
- - "Pentium-Pro" for the Intel Pentium Pro/Celeron/Pentium II.
- - "Pentium-III" for the Intel Pentium III
- and Celerons based on the Coppermine core.
- - "Pentium-4" for the Intel Pentium 4.
- - "K6" for the AMD K6, K6-II and K6-III (aka K6-3D).
- - "Athlon" for the AMD K7 family (Athlon/Duron/Thunderbird).
- - "Elan" for the AMD Elan.
- - "Crusoe" for the Transmeta Crusoe series.
- - "Winchip-C6" for original IDT Winchip.
- - "Winchip-2/Winchip-2A/Winchip-3" for IDT Winchip CPUs
- - "CyrixIII/VIA C3" for VIA Cyrix III or VIA C3.
- - "VIA C3-2 Nehemiah" model 9 and above.
-
- If you don't know what to do, choose "386".
