[PATCH v8 07/16] build: Register '.sld' as an alternative extension to '.scm'.

[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

This is useful when integrating R7RS SRFI libraries into Guile.

* am/bootstrap.am (GOBJECTS_): New variable.
(GOBJECTS): Compute from GOBJECTS_.
<vpath>: Register %.sld to vpath.
(SUFFIXES): Register '.sld' extension.
(.sld.go .scm.go): Add 'sld.go' target to automatic compilation rule.
