YAMAMOTO Takashi cc90d586c0 A workaround for macOS linker
It seems that "ld -r" on macOS doesn't include objects from
libraries for common symbols. Because of that, sim build
ends up with undefined references to globals like g_binfmts
and g_mmheap.

	@(#)PROGRAM:ld  PROJECT:ld64-530
	BUILD 18:57:17 Dec 13 2019
	configured to support archs: armv6 armv7 armv7s arm64 arm64e arm64_32 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em
	LTO support using: LLVM version 11.0.0, (clang-1100.0.33.17) (static support for 23, runtime is 23)
	TAPI support using: Apple TAPI version 11.0.0 (tapi-1100.0.11)
