c455b92483 Set -mlong-calls where needed to get a static clang and lldb 3.8.0
linking. These are too large for a branch instruction to branch from an
earlier point in the code to somewhere later.

This will also allow these to be build with Thumb-2 when we get this
infrastructure.

3c89d6b0e3 Don't override LIB*DIR variables from src.libnames.mk.
In some cases switch to the LIB*SRCDIR value.

These recently were defined in r291327 and r291619.

1e36b7df1a META MODE: Libc++ does in fact need Libcxxrt.
There seems to be no cyclic dependency here.  This partially reverts r283595
which had no explanation for the change.

b791fbe630 META MODE: Don't create .meta files when symlinking sources into the obj directory.
Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file.  There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

d72607e9e2 Import libc++ trunk r224926. This fixes a number of bugs, completes

2205: Problematic postconditions of regex_match and regex_search

aa7703be9c When using an external gcc 4.8+ and not building libstdc++ then create in the objectdir a
fake libstdc++.so and libstdc++.a which is a symlink on libc++ that allow g++ to satisfy
its links dependencies in the least hackish way.
Please note that this hacky libstds++ never get installed on the final system

c354d333b2 Add a c++/v1/tr1 include directory containing symlinks to all of the standard
headrs.

Lots of third-party code expects to find C++03 headers under tr1 because that's
where GNU decided to hide them.  This should fix ports that expect them there.

15d321c5aa Make sure libgcc_s is finished building in _startup_libs before
building libcxxrt with high -j levels.  The workaround in
libc++/Makefile isn't necessary once that race is solved.

MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

To build C++ using libc++, add -stdlib=libc++ to your CXX and LD flags.
