openjdk-8: fix musl build

Add various patches to make it work in musl. Some of them are generic
enough to be applied for all builds, some need to be specific to musl.

+Subject: [PATCH 6/9] hotspot: don't rely on old SysV SIGCLD
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+SIGCLD is the old System V name for SIGCHLD, and not
+all c libraries implement it, e.g. musl-libc, which
+leads to the following compilation error:
+
+| hotspot/src/os/linux/vm/jvm_linux.cpp:157:17: error: 'SIGCLD' was not declared in this scope
+|    "CLD",        SIGCLD,         /* Same as SIGCHLD (System V).  */
+|                  ^~~~~~
+
+Just make it conditional, so the code compiles everywhere.
