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 1/9] hotspot: stop using obsolete isnanf()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Compiling against musl-libc gives the following error:
+| hotspot/src/share/vm/utilities/globalDefinitions_gcc.hpp: In function 'int g_isnan(float)':
+| hotspot/src/share/vm/utilities/globalDefinitions_gcc.hpp:238:39: error: 'isnanf' was not declared in this scope
+|  inline int g_isnan(float  f) { return isnanf(f); }
+|                                        ^~~~~~
+
+isnanf() is obsolete, and musl doesn't implement it. isnan()
+is the right thing to use for all types (float and double),
+replacing isnanf(), even on glibc.
+
+Do so.
