Supports static linking of extensions and encodings again.

Fixes --with-static-linked-ext.

Patch by Google Inc. [ruby-core:45073].

* Makefile.in (ENCOBJS, EXTOBJS): New variables to specify static
  linked libraries. Also reintroduces extinit.o, introduces encinit.o
  introduces encinit.o

* common.mk: Builds static libraries rather than shared objects if
  specified.

* configure.in (LD): new substitution. 
  Avoids PIE if s

* enc/depend: Supports static linked libraries
  (libencs, libenc, libtrans): New target.

* enc/encinit.c.erb: new template to generate the initialization of
  statically linked encodings.

* enc/make_encmake.rb (--module): new flag to specify whether static
  or dynamic.

* transcode_data.h (TRANS_INIT): New macro to get rid of the name
  collision of encoding initializers and transcoder initializers.

* ext/extmk.rb: Fixes the behavior on $extstatic is true.

* lib/mkmf.rb (clean-static): new target to clean up static linked
  libraries.

* ruby.c (process_options): New initializes statically linked
  encodings here.
