Recent FreeBSD versions use LLVM's lld as a linker, not the GNU ld. Their behavior slightly differs, so adapt the build system to handle either one. * The LLVM's linker prints "undefined symbol:" instead of "undefined reference to". Tweak tools/mockup.sh to also look for that message. * The LLVM's linker may only print the first dozen errors (omitting the rest to avoid flooding the screen). tools/update-mocks.sh relies on getting all errors as it extracts the missing symbols' names from the error output and creates mocks for them. Detect if errors were omitted and re-run, telling the linker to not omit any. The GNU linker does not support -error-limit=0, so unfortunately we can't just run with that option unconditionally from the first attempt. * Nit: FreeBSD's sed(1) prints "t" for "\t" instead of a horizontal tab. Use a verbatim tab in the command, instead of "\t" which works on both. Changelog-Fixed: Developer mode compilation on FreeBSD.
