remove GCC 4.2.1 build infrastructure

2020-02-29T03:25:51+00:00

As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date.  At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825.  GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD.  It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff

from the latter.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead

and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

bsd.own.mk needs to be included before Makefil.inc so MK_ARM_EABI is defined

Reorder so that NO_MAN is declared before bsd.own.mk is included and thus

has an effect (not installed a g++.1 manpage over the g++.1(.gz) link
created in ../cc).

Add a WITH_CLANG_IS_CC option for src.conf(5), disabled by default, that

2012-02-29T22:58:51+00:00

installs clang as /usr/bin/cc, /usr/bin/c++ and /usr/bin/cpp.

Note this does *not* disable building and installing gcc, which will
still be available as /usr/bin/gcc, /usr/bin/g++ and /usr/bin/gcpp.  If
you want to disable gcc completely, you must use WITHOUT_GCC.

Update bmake glue to build GCC 4.2.

Also:
        Switch FreeBSD to use libgcc_s.so.1.

        Use dl_iterate_phdr to locate shared objects' exception frame
        info instead of depending on older register_frame_info machinery.
        This allows us to avoid depending on libgcc_s.so.1 in binaries
        that do not use exception handling directly. As an additional
        benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

        Build newly added libgomp.so.1 library, the runtime support
        bits for OpenMP.

        Build LGPLed libssp library. Our libc provides our own
        BSD-licensed SSP callbacks implementation, so this library
        is only built to benefit applications that have hadcoded
        knowledge of libssp.so and libssp_nonshared.a. When linked
        in from command line, these libraries override libc
        implementation.

Start the dreaded NOFOO -> NO_FOO conversion.
