mk: Add CTF infrastructure support.

Platform support is determined by _OPSYS_SUPPORTS_CTF from mk/platform, the
user enables support by setting PKGSRC_USE_CTF=yes, and packages can
explicitly disable support with CTF_SUPPORTED=no or skip certain files with
CTF_FILES_SKIP.

The path to ctfconvert is configured via TOOLS_PLATFORM.ctfconvert.

If all of the requisite variables are enabled, a compiler-specific debug flag
is passed via the wrappers to ensure we have DWARF information to convert,
_INSTALL_UNSTRIPPED is explicitly defined to avoid binaries being stripped
prior to conversion, and the conversion is performed during the install stage.

It is recommended that users who enable the feature also set STRIP_DEBUG=yes
to reduce the final binary size once the conversion has been performed.

This has been used for the past year in Joyent SmartOS builds.  FreeBSD is
marked as supported but is untested.

# $NetBSD: compiler.mk,v 1.90 2018/11/12 14:22:58 jperkin Exp $
#
# This Makefile fragment implements handling for supported C/C++/Fortran
# compilers.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# PKGSRC_COMPILER
#	A list of values specifying the chain of compilers to be used by
#	pkgsrc to build packages.
#
#	Valid values are:
#		ccc		Compaq C Compilers (Tru64)
#		ccache		compiler cache (chainable)
#		clang		Clang C and Objective-C compiler
#		distcc		distributed C/C++ (chainable)
#		f2c		Fortran 77 to C compiler (chainable)
#		icc		Intel C++ Compiler (Linux)
#		ido		SGI IRIS Development Option cc (IRIX 5)
#		gcc		GNU
#		hp		HP-UX C/aC++ compilers
#		mipspro		Silicon Graphics, Inc. MIPSpro (n32/n64)
#		mipspro-ucode	Silicon Graphics, Inc. MIPSpro (o32)
#		pcc		Portable C Compiler
#		sunpro		Sun Microsystems, Inc. WorkShip/Forte/Sun
#				ONE Studio
#		xlc		IBM's XL C/C++ compiler suite (Darwin/MacOSX)
#
#	The default is "gcc".  You can use ccache and/or distcc with
#	an appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc
#	gcc".  You can also use "f2c" to overlay the lang/f2c package
#	over the C compiler instead of using the system Fortran
#	compiler.  The chain should always end in a real compiler.
#	This should only be set in /etc/mk.conf.
#
# COMPILER_USE_SYMLINKS
#	If set to yes, use symlinks for the compiler drivers, otherwise
#	shell scripts are created.  The default is yes.
#
# The following variables may be set by a package:
#
# USE_LANGUAGES

#	Declares the languages used in the source code of the package.
#	This is used to determine the correct compilers to make
#	visible to the build environment, installing them if
#	necessary.  Flags such as --std=c++99 are also added.
#	Valid values are: c, c99, c++, c++03, gnu++03, c++0x, gnu++0x,
#	c++11, gnu++11, c++14, gnu++14, fortran, fortran77, java, objc,
#	obj-c++, and ada.  The default is "c".
#
#       The above is partly aspirational.  As an example c++11 does
#       not force a new enough version of gcc.

# The following variables are defined, and available for testing in
# package Makefiles:
#
# CC_VERSION
#	The compiler and version being used, e.g.,
#
#	.include "../../mk/compiler.mk"
#
#	.if !empty(CC_VERSION:Mgcc-3*)
#	...
#	.endif
