GCC External: Revert r300886, r300904, r300917, r300918

The fix in r300873 is mostly enough. A fix for lib32 will be
committed.separately.

Use a relative symlink for proper --sysroot support.

Sponsored by: EMC / Isilon Storage Division

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.

Sponsored by: EMC / Isilon Storage Division

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.

Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but

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file to be out of date if /bin/sh or /bin/ln are newer than the source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