build: Fix deb build issues with fakeroot

If DESTDIR is set, don't call ldconfig. Assume that DESTDIR is used to
create a binary archive. The ldconfig call should be delegated to the
archive postinst script. This fixes the case where fakeroot wraps 'make
install' causing $EUID to be 0 even though it doesn't have permission to
call ldconfig.

The previous logic in configure.ac to detect and correct libdir
has been removed as it was not completely accurate.  CentOS 64-bit
users should again specifiy --libdir=/usr/lib64 when configuring
to prevent install to /usr/lib.

Updated Makefile:check-old-libdir to check for orphans in
lib64 when installing to lib as well as orphans in lib when installing
to lib64.

Updated Makefile and main/Makefile uninstall targets to remove the
orphans using the new logic.
