Subject: [PATCH] GNUmakefile: add missing shared library symlink

The GNUmakefile install-lib target currently installs the following
symlink:

	libcryptopp.so -> libcryptopp.so.8.6.0

However, it does not create the following symlink:

	libcryptopp.so.8 -> libcryptopp.so.8.6.0

This symlink is necessary at runtime because libcryptopp.so.8 is the
SONAME of the cryptopp library, and therefore this is what the dynamic
loader will search when starting a program that is linked against
cryptopp.

For native compilation, the 'ldconfig' invocation that immediately
follows will create that symlink, so everything works.

For cross-compilation however, ldconfig can't be used, and therefore
LDCONFIG is passed as /bin/true, and therefore it doesn't create the
symlink. So instead, create it directly inside the GNUmakefile,
without relying on ldconfig.
