Ok, got it working with another proposed SQL SELECT. This is a
solution (comes out of an PHP loop, so one could easily have more
than 2 subselects). Thanks for the help to everyone!!

SELECT
year0 AS common_year,
v0.val0 AS v0_value,
v1.val1 AS v1_value
FROM
(
SELECT
year AS year0,
value AS val0
FROM
gdp_capita
WHERE
id_country = 672 AND
value IS NOT NULL
) AS v0,
(
SELECT
year AS year1,
value AS val1
FROM
agri_add_gdp
WHERE
id_country = 672 AND
value IS NOT NULL
) AS v1
WHERE
v1.year1 = v0.year0 AND
v1.year1 = v1.year1
ORDER BY
v0.year0
LIMIT
1
