Building 2.6.20.1 from source

Building 2.6.20.1 from source

[Jim Gifford]

    Trying to build the current 2.6.20.1 on my cobalt. I get this error. 
I have disabled epoll in the config, but still not compiling. Any 
suggestions.

Whops.  You can work around this bug by enabling either CONFIG_MIPS32_N32
or CONFIG_MIPS32_O32.

Guess I should have eyeballed the error message for a few extra nanoseconds,
my answer wasn't quite right.  Enabling the binary compat options would
fix the build but leave the native N64 broken.  Below the fix.
