Eric Bavier 3662909752 build: Generate man pages after compiling Guile objects.
This reduces compilation time since scripts are not compiled twice.
When building with 'make -j4' from a clean repository on an Intel
i5-2540M, compilation time gets from:

real	4m48.708s
user	17m29.892s
sys	0m9.596s

down to:

real	2m23.399s
user	6m48.604s
sys	0m6.420s

* doc.am (subcommand-manual-target): Delete function.
(SUBCOMMANDS): Delete variable.
(sub_command_mans, gen_man): New variables.
(dist_man1_MANS): Add $(sub_commands_mans).
(doc/guix-%.1): New target for sub-commands man pages.  It ensures that
man pages are built only after compiling Guile objects.
(doc/guix-daemon.1): Use $(gen_man).  Build only if BUILD_DAEMON.
(doc/guix.1): Use $(gen_man).  Add $(sub_command_mans) prerequisite.
