Well, for me master is also broken (F32, linux-user only, static):

Compiling C object libqemuutil.a.p/util_compatfd.c.o
../../../Projects/qemu/util/compatfd.c: In function 'qemu_signalfd':
../../../Projects/qemu/util/compatfd.c:103:19: error: 'SYS_signalfd'
undeclared (first use in this function); did you mean 'SYS_signalfd4'?
  103 |     ret = syscall(SYS_signalfd, -1, mask, _NSIG / 8);
      |                   ^~~~~~~~~~~~
      |                   SYS_signalfd4
../../../Projects/qemu/util/compatfd.c:103:19: note: each undeclared
identifier is reported only once for each function it appears in
