The right way to fix this would be to apply https://patchew.org/QEMU/20201027003848.10920-1-mforney@mforney.org/ which got reviewed but never applied (it might need a respin to work with meson) which simply removes the sys/signal.h include and the "does the header exist" test entirely -- there is no platform which needs sys/signal.h. thanks -- PMM

signal.h is equlevant of sys/signal.h on Linux, musl would complain wrong usage of sys/signal.h.
