This value doesn't change on 32bit or 64bit intel processors. On Linux, the value would be x86_64 for 64bit processors and i686 for 32bit processors. The 6 in 686 might be 3,4, or 5 depending on your processor type.

I used Clang analyzer to detect bugs in OpenBIOS around 2010 (r750 to
r752). Clang can be used to build at least openbios-unix on Linux just
with 'make HOSTCC=clang CC=clang'. I'm not sure about other targets
since I haven't had a cross-compiling Clang compiler or native
Sparc/PPC Clang environment.
