libsupc++: Fix typo in symbol map.

This went mostly unnoticed with the deprecation of the GNU toolchain
in tier 1 platforms. Fix it now for the rest.

MFC r257532 (by adrian):

2013-12-30T20:15:46+00:00

Fix this build for clang.

MFC r259730:

To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

MFC r259913:

For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc.

MFC r259927:

Fix pc98 build, by also forcing COMPILER_TYPE in sys/boot/pc98/boot2's
Makefile.

After r255321, clang uses libc++ by default. This leads to a lot of

2013-09-12T21:24:59+00:00

errors when you enable WITH_GNUCXX to build libstdc++, since it will
include C++ headers from the libc++ installation under ${WORLDTMP}, and
those are not compatible with libstdc++ at all.

To fix this, add -stdlib=libstdc++ to CXXFLAGS when building libstdc++
(and its companion libsupc++) with clang.

Fix some symbol version mismatches between libstdc++ and libsupc++/libcxxrt

2013-01-28T11:12:49+00:00

that were causing the runtime and STL libraries to see different versions of
various classes and functions when libstdc++ is used as a filter.

Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in
-STABLE for testing and is not used by anything unless explicitly enabled by
the end user.  No default compiler configurations use it.

libc++ will need to be recompiled after this change.  make buildworld will do
this automatically, but make in lib/libc++ will not necessarily work unless the
new libcxxrt is installed first.
