Subject: [PATCH] tools/usbip: fixes build with musl libc toolchain

Mime-version: 1.0

Content-type: text/plain; charset=UTF-8

Content-transfer-encoding: 8bit

Git-commit: 77be4c878c72e411ad22af96b6f81dd45c26450a

Patch-mainline: v4.16-rc1

References: bsc#1051510

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
