It already used the right flags for compiling, this is only for linking. Also, the meson setup already did this correctly. Back-patch of v18 commit 365b5a345 into older supported branches. At the time we were only aware of trouble in v18, but as shown by buildfarm member siren, older branches can hit the problem too.
