x86/purgatory: use approprate -m64/-32 build flag for arch/x86/purgatory
Thomas reported that build of x86_64 kernel was failing for him. He is
using 32bit tool chain.
Problem is that while compiling purgatory, I have not specified -m64
flag. And 32bit tool chain must be assuming -m32 by default.
Following is error message.

arch/x86/purgatory/purgatory.c:1:0: error: code model 'large' not supported in
the 32 bit mode
Fix it by explicitly passing appropriate -m64/-m32 build flag for
purgatory.
