      Description

        Building JDK with musl libc gives the error:
        ---------------------
        src/java.base/linux/native/libnet/linux_close.c:63:25: error: '__SIGRTMAX' undeclared here (not in a function); did you mean 'SIGRTMAX'?
           63 | static int sigWakeup = (__SIGRTMAX - 2);
              | ^~~~~~~~~~
              | SIGRTMAX
        ---------------------

        This is because musl libc does not define __SIGRTMAX constant.

        Simple replacing __SIGRTMAX to SIGRTMAX does not work either because SIGRTMAX is defined as function and not as a constant:
