This text is more one for a cover-letter?

Or (better?):

    The meson build provides no 'disable-valgrind' option but checks
    for the availability of valgrind/valgrind.h, so add an optional
    valgrind dependency instead.

missing:

    - -Dgobject-cast-checks=disabled

Not sure if it is the best to disable these three checks above
as default...the meson_options.txt files states 'auto = enabled
for development, disabled for stable releases'...so maybe you
are right with this decision...

Why not the short form as above for libunwind? e.g.
        ... \
        $(if $(BR2_PACKAGE_VALGRIND),valgrind)

Otherwise looks very similar to my draft from April, see [1]
