Log:	drop -mmacosx-version-min=10.4 when building on Mac OS X

	Just passing -mmacosx-version-min isn't sufficient for ensuring
	compatibility with 10.4. In order to make prevent the compiler and
	linker from using anything introduced in a later OS, a sysroot
	should be specified, pointing to an appropriate SDK.

	However, PyPy as-is doesn't even run terribly well on the latest
	(and most popular) release of Mac OS X. Supporting older releases
	amounts to wishful thinking.

	In theory, compiler and linker produce better code when targeting
	the latest OS, but any such improvements will probably be minuscule.
