musl: add patch for mips dynlinker regression

COOKBOOK: update, tell more about /src
socat: enable help output on command line

$ socat -h
2014/07/07 11:59:10 socat[24013] E unknown option "-h"; use option "-h" for help

^ not very helpful

in socat.c:
 #if WITH_HELP
       case '?':
       case 'h':
            socat_usage(stdout);

so it turns out that --disable-help wasn't the best idea.
socat: fix for x-compile
add socat to world
move KEEP/package.template -> KEEP/pkg_skel/autoconf

pkg_skel will contain pkg templates for several build system types.
add template for perl/cpan pkg
add template for python pkg
README.md: update paragraph mentioning package templates
git: fix path where perl modules end up

i have not been able to determine without big effort where the
perl "syslibdir" is queried, so simply moving it to the right place
has to suffice for the moment.
