Could not build clang-3.7 (and any other versions of clang), even though buildsarch x86_64 is prescribed in macports.conf.

Make is trying to install multiple RT_tools for useless OS X 10.4

(It seems to me the problem is here):

...
# FIXME: Eventually, we want some kind of configure support for this. We want to
# build/install runtime libraries for as many targets as clang was configured to
# support.
RuntimeDirs :=
ifeq ($(OS),Darwin)
RuntimeDirs += darwin macho_embedded
RuntimeLibrary.darwin.Configs := \
	eprintf.a 10.4.a osx.a cc_kext.a \
	asan_osx_dynamic.dylib \
	profile_osx.a \
	ubsan_osx_dynamic.dylib

IOS_SDK := $(shell xcrun --show-sdk-path -sdk iphoneos 2> /dev/null)
IOSSIM_SDK := $(shell xcrun --show-sdk-path -sdk iphonesimulator 2> /dev/null)

ifneq ($(IOS_SDK)$(IOSSIM_SDK),)
RuntimeLibrary.darwin.Configs += ios.a profile_ios.a
endif
