build: fix mutex detection when building bdb on macOS
Starting with the Clang shipped with Xcode 12, Apple has enabled -Werror=implicit-function-declaration by default. This causes bdbs mutex detection to fail when building on macOS (not cross-compiling): 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: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration] Append -Wno-error=implicit-function-declaration to cflags so that -Wimplicit-function-declaration returns to being a warning, and the configure checks will succeed. Fixes #19411.
