Almostly equal.  But they can be different while cross
compiling.

Although many extension libraries (even ext/extmk.rb and
lib/mkmf.rb) uses RUBY_PLATFORM in their extconf.rb to determin
the target platform, I consider it shouldn't.

Moreover, PLATFORM, VERSION and RELEASE_DATE have been
deprecated long ago, so never use them.
