It is only used by `Makefile.include` and should not be used by sub-make
instances.
This is required to prevent evaluating `LINKFLAGS` when not needed and a
required step to not evaluate it on the host with for example `avr-ld`
when building in docker.
I checked usage with:
git grep -e '(LINKFLAGS)' -e '{LINKFLAGS}'
Packages may be using it but `LINKFLAGS` is a RIOT way of naming
things and even if `generate-xcompile-toolchain` uses `LINK` it does not
use `LINKFLAGS`.

There was a problem hiding this comment.
The provided reason for this change and the change itself make both sense.
I also tested #10854 and also confirm that this PR is fixing the bug (I already noticed it some time ago but didn't understand why it was failing).
The build CI is green, so the change is not introducing any problems.

Look at the usages on
LINKFLAGSwithgit grep -e '(LINKFLAGS)' -e '{LINKFLAGS}'and notice nothing is using it exceptMakefile.includeandmakefiles/info.inc.mk.I did not look in the packages yet but will if the CI build fails.
