try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

by defining a LLVM_COMPACT_SENTINELS symbol to 0 or 1 in config.h.
I'm asking for 3 favors:
- may an autofoo expert look at this and suggest improvements?
- may a cmake expert suggest analogous functionality for config.h?
- may somebody with the right autofoo mix regenerate configure? (mine is too new)
Thanks!

Note that configure was edited by hand. Will somebody with the correct version of autoconf please regenerate?

Windows variant, strerror_s, but I couldn't test that.
I'll update configure and config.h.in in a subsequent patch.

initialization of all targets (InitializeAllTargets.h) or assembler
printers (InitializeAllAsmPrinters.h). This is a step toward the
elimination of relinked object files, so that we can build normal
archives.

Also, there were a bunch of flags with no text in --help because the square
brackets were in the wrong place. I've fixed those too.

Regenerate configure for these changes.

Should now work when building with objdir != srcdir and when llvm-gcc is not
available.
Thanks to Duncan Sands for testing and advice!

Configure was not actually regenerated, but the change last time only touched
this one line, so I'm being lazy and cheating by fixing it manually.

This changes the interpreter to use libffi. After this patch, the interpreter
will barely be able to call any external functions if built on a system without
libffi installed (just enough to pass 'make check' really). But with libffi,
we can now call any function that isn't variadic or taking a struct or vector
parameter (but pointer to struct is fine). Patch by Alexei Svitkine!
