On macOS, use -isysroot in link steps as well as compile steps.
We previously put the -isysroot switch only into CPPFLAGS, theorizing
that it was only needed to find the right copies of include files.
However, it seems that we also need to use it while linking programs,
to find the right stub ".tbd" files for libraries. We got away
without that up to now, but apparently that was mostly luck. It may
also be that failures are only observed when the Xcode version is
noticeably out of sync with the host macOS version; the case that's
prompting action right now is that builds fail when using latest Xcode
(12.2) on macOS Catalina, even though it's fine on Big Sur.
Hence, add -isysroot to LDFLAGS as well. (It seems that the more
common practice is to put it in CFLAGS, whence it'd be included at
both compile and link steps. However, we can't mess with CFLAGS in
the platform template file without confusing configure's logic for
choosing default CFLAGS.)
This should be back-patched, but first let's see if the buildfarm
likes it on HEAD.
