Test passes after manually building the native component ([as with the 17u backport](https://github.com/openjdk/jdk17u-dev/pull/506)):


 $  pushd test/jdk/java/lang/RuntimeTests/loadLibrary/exeLibraryCache
 $  cc  exeLibraryCache.c -o LibraryCache
 $  popd
 $  $JT_HOME/bin/jtreg -jdk:build/macosx-x86_64-server-release/images/jdk  \
 -nativepath:test/jdk/java/lang/RuntimeTests/loadLibrary/exeLibraryCache  \
test/jdk/java/lang/RuntimeTests/loadLibrary/exeLibraryCache/LibraryFromCache.java
