add gdb-pre-inst-guile

* configure.in:
* gdb-pre-inst-guile.in: Add gdb-pre-inst-guile, because I'm tired of
  typos. You can run it just like Guile. For compiling, you might try
  GUILE=./gdb-pre-inst-guile scripts/compile foo.scm.

+# Commentary:
+
+# Usage: pre-inst-guile [ARGS]
+#
+# This script arranges for the environment to support, and eventaully execs,
+# the uninstalled binary guile executable located somewhere under libguile/,
+# passing ARGS to it.  In the process, env var GUILE is clobbered, and the
+# following env vars are modified (but not clobbered):
+#   GUILE_LOAD_PATH
+#   LTDL_LIBRARY_PATH
+#
+# This script can be used as a drop-in replacement for $bindir/guile;
+# if there is a discrepency in behavior, that's a bug.
+
+# Code:
+
+# env (set by configure)
+top_builddir="@top_builddir_absolute@"
+
+# set GUILE (clobber)
+GUILE=${top_builddir}/libguile/.libs/lt-guile
+export GUILE
+
+# do it
+exec ${top_builddir}/pre-inst-guile-env gdb --args $GUILE "$@"
+
+# never reached
+exit 1
+
+# pre-inst-guile ends here
