In a Mac OS X Lion 10.7.4 MacBook Air, when building p7zip-9.20.1 with -O4, in
linking stage, ld gave the following error message:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Xcode 4.3.2 and command-line utilities are installed. p7zip could be built with
-O4 cleanly in Linux.

The makefile.machine is:

OPTFLAGS=-O4

# don't use -DNDEBUG in order to use MacOSX wxWidgets

ALLFLAGS=${OPTFLAGS}  \
        -DENV_MACOSX \
        -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE \
        -D_REENTRANT -DENV_UNIX \
        $(LOCAL_FLAGS)

CXX=/opt/bin/clang++ $(ALLFLAGS)
CC=/opt/bin/clang $(ALLFLAGS)
LINK_SHARED=-bundle

LOCAL_LIBS=-framework CoreFoundation
LOCAL_LIBS_DLL=$(LOCAL_LIBS)

OBJ_CRC32=$(OBJ_CRC32_C)
