Use separate sed expressions to escape auto-load directories.
Not all sed implementations support alternation via \| in the default
regular expressions. Instead, resort to separate sed expressions via
-e for $debugdir and $datadir. This fixes the default setting of the
auto-load directories on FreeBSD. Previously on FreeBSD the sed
invocation was a no-op causing the debugdir and datadir values to be
expanded yielding an autoload path of ':${prefix}/share/gdb'.
gdb/ChangeLog:
* configure: Re-generate.
* configure.ac: Use separate sed expressions to escape variables
in auto-load directories.
