* Bootstrap llvm-tblgen and clang-tblgen with a minimal llvm static
library, that has no other dependencies.
* Roll up all separate llvm libraries into one big static libllvm.
* Similar for all separate clang and lldb static libraries.
* For all these libraries, generate their .inc files only once.
* Link all llvm tools (including extra) against the big libllvm.
* Link clang and clang-format against the big libllvm and libclang.
* Link lldb against the big libllvm, libclang and liblldb.
N.B.: This is work in progress, some details may still be missing.
It also heavily depends on bsd.*.mk's support for SRCS and DPSRCS with
relative pathnames, which apparently does not always work as expected.
For building llvm, clang and lldb though, it seems to work just fine.
The main idea behind this restructuring is maintainability and build
peformance. The previous large number of very small libraries, each
with their own generated files and dependencies was slow to traverse
and hard to understand.
Possible future improvements:
* Only build certain targets, e.g. for most regular users having just
one target will be fine. This will shave off some build time.
* Building the big llvm, clang and lldb libraries as shared (private)
libraries.
* Adding other components from the LLVM project, such as lld.
Update build glue for clang and the llvm/clang extras.2016-08-19T17:55:34ZDimitry Andricdim@FreeBSD.org2016-08-19T17:55:34Zurn:sha1:7fff4413af5f22ce98eac43f9a94cfe77d5fcef1DIRDEPS_BUILD: Update clang dependencies after r296417.2016-03-08T21:26:44ZBryan Drewerybdrewery@FreeBSD.org2016-03-08T21:26:44Zurn:sha1:f51eac06ce2352c576777d0a8e2b42a8d2e528d4

DIRDEPS_BUILD: Regenerate without local dependencies.2016-02-24T17:20:11ZBryan Drewerybdrewery@FreeBSD.org2016-02-24T17:20:11Zurn:sha1:bd18fd57db1df29da1a3adf94d47924a977a29c2
These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

Add META_MODE support.2015-06-13T19:20:56ZSimon J. Gerratysjg@FreeBSD.org2015-06-13T19:20:56Zurn:sha1:ccfb965433c67f3bda935a3cdf334be2e3c4348d
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
