Migrate to a new way of dealing with building from old revisions of FreeBSD. This method attempts to centralize all the necessary hacks or work arounds in one of two places in the tree (src/Makefile.inc1 and src/tools/build). We build a small compatibility library (libbuild.a) as well as selectively installing necessary include files. We then include this directory when building host binaries. This removes all the past release compatibilty hacks from various places in the tree. We still build on tip of stable and current. I will work with those that want to support more, although I anticipate it will just work. Many thanks to ru@, obrien@ and jhb@ for providing valuable input at various stage of implementation, as well as for working together to positively effect a change for the better.

-legacy and /.../legacy/... looks better than build or bootstrap in the logs, so use that instead. Submitted by: obrien.

r235638 is not the clean way to add support for building on ancient FreeBSD versions. Instead use Imp's good work on "legacy" and follow the outcome of the previous TRB discussions on this topic. Now use the libc getline() if it exists, and only where it doesn't create a bootstraping version.

build: Add legacy support for futimens() and utimensat(). In order to allow using utimensat() in install(1), add futimens() and utimensat() to -legacy. The files futimens.c and utimensat.c are modified copies of the files under lib/libc/sys/ since the libc versions use symbols that do not exist in the libc on the build system (sys_futimens and sys_utimensat) . I expect the next non-sweeping change to both sets of files to be to delete them, anyway. This will allow reverting r299942 (which is a revert of r299850) enabling nanosecond timestamps in install(1). Reviewed by: bdrewery

_WITH_REALLOCARRAY!= grep -c reallocarray /usr/include/stdlib.h || true
Provide reallocarray() in -legacy, if needed, to allow building head on previous releases. Also add a stdlib.h wrapper, which declares the function, otherwise the compiler may assume it returns int, which can cause segfaults on LP64 architectures.

Add hacks that I use to test cross-builds (by building on native and foreign architectures and comparing products). They eliminate most of the differences caused by different object directory paths, timestamping, and identification. (Note WORLDTMP was renamed to ${OBJTREE}${.CURDIR}/tmp.)
