0fbf051fec723f86f49ab14ea15c91bb1435c656 depends: fix BDB compilation on OpenBSD (Sebastian Falbesoner)
Pull request description:
Compiling C++ code with `-D_XOPEN_SOURCE=600` causes problems on OpenBSD. If that define is set, the C++ standard header detection routine in BDB's configure script fails due to a missing type name for `locale_t` (see https://gist.github.com/theStack/b41884e31ebc5cdca3220bcaa674cb70 for the relevant config.log part).
This results in `HAVE_CXX_STDHEADERS` not being defined, which then it turn leads to the inclusion of `<iostream.h>` (rather than `<iostream>`), which doesn't exist, as described in #28963.
According to a mailing list post discussing a similar problem [1], "OpenBSD provides the POSIX APIs by default", so we don't need this define anyway and can remove it. This fixes the BDB build problem as described in issue #28963. See also f87e75ae71 for a similar fix for google's flatbuffer project.
Tested on OpenBSD 7.4 with clang 13.0.0. Fixes#28963.

e037c4fe0914d8fa9149ce7532c0d70f738e79e9 depends: always configure with --with-pic (fanquake)
Pull request description:
We currently do this sporadically. Not only amongst packages, but across OS's, i.e sometimes it's done for BSDs/Android, and sometimes not.
Configure with `--with-pic` globally instead. I think this generally makes more sense, and should not have any downsides.

bcff8e21b1bb360c3cf1e1d2e1a2a54ec7581720 build: only pass --disable-dependency-tracking to packages that understand it (fanquake)
Pull request description:
By blanket passing `--disable-dependency-tracking` to all depends packages we end up with warnings (i.e in `bdb` or `freetype`) like:
```bash
configure: WARNING: unrecognized options: --disable-dependency-tracking
```
Instead, only pass it to packages that actually understand it. Related to https://github.com/bitcoin/bitcoin/issues/16354.
More info on `--disable-dependency-tracking` available [here](https://www.gnu.org/software/automake/manual/html_node/Dependency-Tracking.html).
This PR also adds `--enable-option-checking` as a configure option to all applicable packages.

d0a829e9632379e42f0be5c554e3b692f0d14a95 build: fix mutex detection when building bdb on macOS (fanquake)
Pull request description:
Starting with the Apple Clang shipped with Xcode 12, [Apple has enabled -Werror=implicit-function-declaration by default](https://developer.apple.com/documentation/xcode-release-notes/xcode-12-release-notes):
> Clang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (49917738)
This causes bdbs mutex detection to fail when building on macOS (not cross-compiling):
```bash
checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation
```
as previously emitted warnings are being turned into errors. i.e:
```bash
configure:18704: checking for mutexes

```
Append `-Wno-error=implicit-function-declaration` to `cflags` so that `-Wimplicit-function-declaration` [returns to being a warning](https://clang.llvm.org/docs/UsersManual.html#cmdoption-wno-error), and the configure checks succeed.
Fixes#19411.
