ce00342bb2 Move external GCC compiler hacks to bsd.sys.mk.
This allows respecting -nostdinc, -nostdinc++ and -nostdlib before
making the decision to add in -isystem, etc.  The -isystem flags
are problematic for building lib/libc++ and lib/libcxxrt which wants
to only use its own headers.

More information the need of these flags can be found at
https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html

This also reverts r300873.

09210a281c After r300770, for libc++ and libcxxrt, use -isystem instead of -I.
This should fix builds with external gcc toolchains from ports, which
also use -isystem to work around problems with gcc's --sysroot
implementation.  Thanks to Bryan Drewery for this workaround.

c455b92483 Set -mlong-calls where needed to get a static clang and lldb 3.8.0

earlier point in the code to somewhere later.

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

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file to be out of date if /bin/sh or /bin/ln are newer than the source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.
