json-c: needs __sync_val_compare_and_swap_4
While json-c itself builds fine on platforms that don't provide the
__sync atomic built-ins, it does use them. json-c doesn't fail to
build because only a library is built, so such function calls are left
unresolved. But as soon as it gets used in another package linked in a
program, linking will fail due to the missing
__sync_val_compare_and_swap_4() function.
To fix this, we make json-c depend on BR2_TOOLCHAIN_HAS_SYNC_4, and
propagate to the reverse dependencies:
- json-c
- fastd
- pulseaudio
- efl
- espeak
- gst-plugins-good
- gst1-plugins-good
- mpd
- rsyslog
- ubus
Note that pulseaudio already had a BR2_ARCH_HAS_ATOMICS dependency,
which we are keeping for the moment, and will clean-up in a subsequent
commit.
This commit will also fix packages that could optionally use json-c,
and therefore fixes build failures like:
