afef99a299 remove the 'weak debug info' notes from the README 
Debug symbols work anyway as long you *don't* build the binary in a single step:

o32-clang++ test.cpp -g3           # causes dsymutil invocation

o32-clang++ test.cpp -g3 -c        # causes *no* dsymutil invocation
o32-clang++ -g3 test.o -o test     # causes *no* dsymutil invocation

same with gcc.

Getting line numbers may require you to copy the object files (*.o) onto the system you are debugging on.

2a4842f3cc add libc++ build script 
update README with libc++ build instructions and samples
fix mavericks SDK download link (pointed to 10.8)
build xar only for <=10.5
add -g0 to the clang invocation command to avoid dsymutil from being run (debugging is not supported, but I guess you don't want to debug the resulting binaries anyway if you build them on a non OS X system)
attempt to make the toolchain less path dependent (gcc still breaks though, because of hardcoded paths), but clang and cctools can be moved now
update cctools to 845
add DISABLE_LTO_SUPPORT option (DISABLE_LTO_SUPPORT=1 ./build.sh) to disable linking against libLTO.so
add support for 32 bit systems
add FreeBSD support
update PACKAGE script

e7160ea10a there is an issue in the OSX SDK stdarg.h header file which causes va_copy not to be defined with -std=c++11, so use clang's fixed intrinsic header instead 
diff:

-#if __STDC_VERSION__ >= 199900L || !defined(__STRICT_ANSI__)
+#if __STDC_VERSION__ >= 199900L || __cplusplus >= 201103L || !defined(__STRICT_ANSI__)
 #define va_copy(dest, src)  __builtin_va_copy(dest, src)
 #endif

dc8c4719c3 enforce building gcc with clang - otherwise building gcc will fail (probably a configuration bug in gcc) 
building gcc with gcc (targeting OS X on linux) causes the following errors:

error 1:

g++   -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings   -DHAVE_CONFIG_H -static-libstdc++ -static-libgcc  -o xg++ \

error 2:

g++ -c  -DIN_GCC_FRONTEND -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings   -DHAVE_CONFIG_H -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include  -I../../gcc/../libdecnumber -I../../gcc/../libdecnumber/dpd -I../libdecnumber -I../../gcc/../libbacktrace    cc1-checksum.c -o cc1-checksum.o
cc1plus: error: unrecognized command line option '-mmacosx-version-min=10.4'

after fixing the -mmacosx-version-min issue in the gcc/specs file, I get the following weird error (gmp is indeed installed):

g++ -c  -DIN_GCC_FRONTEND -g  -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings   -DHAVE_CONFIG_H -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include  -I../../gcc/../libdecnumber -I../../gcc/../libdecnumber/dpd -I../libdecnumber -I../../gcc/../libbacktrace    cc1-checksum.c -o cc1-checksum.o
In file included from cc1-checksum.c:2:0:
../../gcc/system.h:641:17: fatal error: gmp.h: No such file or directory
 #include <gmp.h>

all these errors do not appear when clang is used for building gcc.
