This change allows the user to once again override the C++ standard, restoring
high-level pre-r345708 behavior.
This also unbreaks building lib/ofed/libibnetdisc/Makefile with a non-C++11
capable compiler, e.g., g++ 4.2.1, as the library supported being built with
older C++ standards.

CXXSTD was added as the C++ analogue to CSTD.
CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`,
otherwise for older versions of g++.
This change standardizes the CXXSTD variable, originally added to
googletest.test.inc.mk as part of r345203.
As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`.
Notes:
This value is not sanity checked in bsd.sys.mk, however, given the two
most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is
likely to work with both toolchains. This method will be refined in the future
to support more variants of C++, as not all versions of clang++ and g++ (for
instance) support C++14, C++17, etc.
Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD.
Example:
Before this commit:
```
CXXFLAGS+= -std=c++14
```
After this commit:
```
CXXSTD= c++14
```

When a review is closed via Phabricator it updates the patch attached to the
review. I downloaded the raw patch from Phabricator, applied it, and repeated
my mistake from r345704 by accident mixing content from D19732 and D19738.
For my own personal sanity, I will try not to mix reviews like this in the
future.

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.

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.

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file to be out of date if /bin/sh or /bin/ln are newer than the source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