Revert patch that breaks libgcj shared library on powerpc:

	* gnu/java/security/provider/Gnu.java: Reverse referencing all
	implementation classes by using Class.getName(). Uses Strings again.
	* gnu/java/security/der/DEREncodingException.java,
	gnu/java/security/provider/DERReader.java,
	gnu/java/security/provider/DERWriter.java,
	gnu/java/security/provider/DSAKeyPairGenerator.java,
	gnu/java/security/provider/DSAParameterGenerator.java,
	gnu/java/security/provider/DSAParameters.java,
	gnu/java/security/provider/DSASignature.java,
	gnu/java/security/provider/GnuDSAPrivateKey.java,
	gnu/java/security/provider/GnuDSAPublicKey.java,
	gnu/java/security/provider/MD5.java,
	gnu/java/security/util/Prime.java: Removed.
	* Makefile.am (ordinary_java_source_files): Remove above files.
	* Makefile.in: Regenerate.
	* gnu/java/security/provider/DefaultPolicy.java
	(getPermissions): Revert to maintaining static class variable of
	Permissions.
	* gnu/java/security/provider/SHA.java
	(engineUpdate): Revert algorithm change.
	(engineDigest): Revert algorithm change.
