Since the "-l<lib>" flags in the build.ninja file are passed in
"--start-group"/"--end-group" flags, there should be no need to have any
library listed twice, even if there are circular dependencies. Therefore we
can eliminate duplicates. For speed, rather than deduplicating at the end
of the process, it's faster to not add the duplicate flags in the first
place.
This should help fix#2150
OpenBSD doesn't have any support for the compiler sanitizers yet.
While this may change in the future, better fix test suite run in "failfast"
mode for now. This can be revisited once (if) we get support in the future.

* If clone-recursive is specified, populate submodules only after
the specified revision/branch has been checked out. Fixes#4996
* Update submodules recursively on `meson subprojects update`
OpenBSD does not link libc into shared libraries by default to avoid binding
libraries to specific libc majors. So prevent passing "-Wl,--no-undefined" or
"-zdefs" when linking (those options have always suffered false positives on
this operating system).
We need to match the "clang --version" output on OpenBSD:
$ clang --version | head -1
OpenBSD clang version 7.0.1 (tags/RELEASE_701/final) (based on LLVM 7.0.1)
The documentation for this change was left out of its implementation in
commit b4aee4675a and was later documented
in commit f831c05b55 as if it had always
existed.
