[bug#36477] [PATCH v3 20/48] gnu: openldap: Fix cross-compilation.

[Mathieu Othacehe]

* gnu/packages/openldap.scm (openldap)[inputs]: Move groff from here to ...
[native-inputs]: ... here. Also add bdb and automake.
[arguments]: Add cross-compilation specific configure-flags. Do not strip when
cross-compiling. Add a new fix-configure phase to update outdated config.sub
and config.guess. Add a fix-cross-gcc phase to set CC variable to
cross-compiler name when cross-compiling.
