#69782: legacy-support: Minor issues with ARCHFLAGS in the Makefile

Not a real problem, and easy to workaround, but I wanted to report it
anyway.
In the Makefile it does the following:
{{{
FORCE_ARCH ?=
ARCHFLAGS ?=
LIPO ?= lipo
CC ?= cc $(ARCHFLAGS)
CFLAGS ?= -Os -Wall -Wno-deprecated-declarations
DLIBCFLAGS ?= -fPIC
SLIBCFLAGS ?=
CXX ?= c++ $(ARCHFLAGS)
CXXFLAGS ?= -Os -Wall
}}}
So building with "make FORCE_ARCH=i368 ARCHFLAGS='-arch i368'" I expected
to get a proper i386 build of the library, but I ended up with a x86_64
one anyway. It seems that "$(ARCHFLAGS)" is not expanded in the "CC ?= …"
and "CXX ?= …" lines and simply ends up empty, hence the it progresses
with a native arch build. Switching both lines from "?=" to just "=" makes
things work (ultimately I just passed CC and CXX including the arch
parameter as arguments to make instead using the ARCHFLAGS variable).

(XCode 7.2/ OS X 10.10.5 Yosemite)
Unrelated to the actual issue above I think the BUILDING.txt could need
some clarification how things work. I sounds a bit confusing. E.g. I
assumed it would work with just FORCE_ARCH. It also could mention the
supported arches, so one doesn't have to dig it out of the Makefile source
code.
