Well, $(call cc-option,-msym32) can be used safely.  AFAIK -msym32 was
added to gcc 4.0 which was released on Apr 2005, and binutils 2.16 was
release on May 2005.  So if gcc accepted -msym32 we can assume
binutils accept too.

I think killing BUILD_ELF64 and adding -msym32 automatically are good
idea.  Also I do not think __pa_page_offset() is critical for
performance.
