Subject: [PATCH] libguile/Makefile.am: Fix race condition in install-data-hook

During parallel installation (`make -j install`), `install-data-hook`
might execute before the libraries are actually installed to the
destination directory. Since the hook attempts to read the installed
library names from `$(DESTDIR)$(libdir)`, this can lead to build failures.

This patch adds an explicit dependency on `install-libLTLIBRARIES` to
ensure the libraries exist before the hook runs. Consequently, the explicit
creation of `$(libdir)` is no longer required as `install-libLTLIBRARIES`
handles it.

* libguile/Makefile.am (install-data-hook): Add dependency on
install-libLTLIBRARIES. Remove redundant directory creation.
