[ Upstream commit 77be4c878c72e411ad22af96b6f81dd45c26450a ]
Indeed musl doesn't define old SIGCLD signal name but only new one SIGCHLD. SIGCHLD is the new POSIX name for that signal so it doesn't change anything on other libcs.
This fixes this kind of build error:
usbipd.c: In function ‘set_signal’: usbipd.c:459:12: error: 'SIGCLD' undeclared (first use in this function) sigaction(SIGCLD, &act, NULL); ^~~~~~ usbipd.c:459:12: note: each undeclared identifier is reported only once for each function it appears in Makefile:407: recipe for target 'usbipd.o' failed make[3]: *** [usbipd.o] Error 1
