This is caused by a missing libstdc++.a library.
This is installed as part of a specific package
(e.g. libstdc++.so.devel.386).
By default some 64bit Linux versions (e.g. Fedora)
only install the 64bit version of the libstdc++ package.
By default some 64-bit Linux versions (e.g. Fedora)
only install the 64-bit version of the libstdc++ package.
Various parts of the JDK build require a static
link of the C++ runtime libraries to allow for maximum
portability of the built images.

// define a class but do not make it known to the class loader or system dictionary
// - host_class: supplies context for linkage, access control, protection domain, and class loader
// - data: bytes of a class file, a raw memory address (length gives the number of bytes)
// - cp_patches: where non-null entries exist, they replace corresponding CP entries in data
// When you load an anonymous class U, it works as if you changed its name just before loading,
// to a name that you will never use again. Since the name is lost, no other class can directly
// link to any member of U. Just after U is loaded, the only way to use it is reflectively,
// through java.lang.Class methods like Class.newInstance.
// Access checks for linkage sites within U continue to follow the same rules as for named classes.
// The package of an anonymous class is given by the package qualifier on the name under which it was loaded.
// An anonymous class also has special privileges to access any member of its host class.
// This is the main reason why this loading operation is unsafe. The purpose of this is to
// allow language implementations to simulate "open classes"; a host class in effect gets
// new code when an anonymous class is loaded alongside it. A less convenient but more
// standard way to do this is with reflection, which can also be set to ignore access
// restrictions.
// Access into an anonymous class is possible only through reflection. Therefore, there
// are no special access rules for calling into an anonymous class. The relaxed access
// rule for the host class is applied in the opposite direction: A host class reflectively
// access one of its anonymous classes.
// If you load the same bytecodes twice, you get two different classes. You can reload
// the same bytecodes with or without varying CP patches.
// By using the CP patching array, you can have a new anonymous class U2 refer to an older one U1.
// The bytecodes for U2 should refer to U1 by a symbolic name (doesn't matter what the name is).
// The CONSTANT_Class entry for that name can be patched to refer directly to U1.
// This allows, for example, U2 to use U1 as a superclass or super-interface, or as
// an outer class (so that U2 is an anonymous inner class of anonymous U1).
// It is not possible for a named class, or an older anonymous class, to refer by
// name (via its CP) to a newer anonymous class.
// CP patching may also be used to modify (i.e., hack) the names of methods, classes,
// or type descriptors used in the loaded anonymous class.
// Finally, CP patching may be used to introduce "live" objects into the constant pool,
// instead of "dead" strings. A compiled statement like println((Object)"hello") can
// be changed to println(greeting), where greeting is an arbitrary object created before
// the anonymous class is loaded. This is useful in dynamic languages, in which
// various kinds of metaobjects must be introduced as constants into bytecode.
// Note the cast (Object), which tells the verifier to expect an arbitrary object,
// not just a literal string. For such ldc instructions, the verifier uses the
// type Object instead of String, if the loaded constant is not in fact a String.
