But the upstream commit causes the build to bail out as soon as -Ofast
is in the CFLAGS, so even if you specify -Ofast -fno-finite-math-only,
systemd's meson machinery will bail out.

So your other idea of:

SYSTEMD_CFLAGS = $(filter-out -Ofast,$(TARGET_CFLAGS))

certainly looks very relevant.

Fabrice, could you give it a try?
