hotspot.m4: 296: Comment is misleading. Should just be removed.

CompileJavaModules.gmk: Use of -g flag for java compilation is 
controlled globally. Please remove.

Main.gmk: buildtools-hotspot should be declared inside the 
CREATING_BUILDJDK conditional like all other buildtools targets.

The extra exports from java.base needs to go in a new 
jdk/src/java.base/share/classes/module-info.java.extra since the module 
jdk.vm.compiler is optional.

Lib-jdk.aot.gmk: Please inline LDFLAGS and LIBS and add $(LIBS_JDKLIB) 
to LIBS since that will provide -lc on Solaris automatically. No need to 
set DEBUG_SYMBOLS or STRIP_SYMBOLS as the defaults should be correct and 
controlled globally.
