gcc: correct LINK_SPEC for m68k

We need to allow undefined symbols to link libgcc now...

gcc4: revert partially 419211519c79edc7af6fca9c6a3233129ec54d7d.

"* LINK_SPEC: Pass "-shared" to the linker only if it was passed to gcc; output
position-independent executables by default;" is reverted to workaround a
link failure on gcc4 with binutils 2.26: add-ons objects would fail to link
against an executable (being no more a shared object). This is possibly temporary
until the need for executable as shared objects is fully reviewed.

gcc2, gcc4: Correct LINK_SPEC

Correct LINK_SPEC so it

* Sets appropriate dynamic-link options for any type of dynamically
linked executable, not only position-independent ones.
* Does not omit these options if "-pie" is specified by the user.
* Recognizes the "-static" option.
* Includes a hyphen previously missing from "--no-undefined".

gcc: Allow the user to build non-PI executables

* CC1_SPEC: Remove non-existent "no-fpic" command-line option; add
"fno-PIC" and "fno-PIE" as options that disable the generation of
position-independent code; use "-fPIC" by default.
* LINK_SPEC: Pass "-shared" to the linker only if it was passed to gcc; output
position-independent executables by default; when linking executables, allow
undefined symbols in shared libraries and export all symbols (to match the
behaviour of "-shared").

Don't switch on -shared if the user specifies -r.

* Follow up to btrev43090, to include platforms missed in
original commit.

* define __STDC_ISO_10646__ to '201103' in order to indicate that
Haiku's wchar_t supports the Universal Character Set (UCS) defined
by the ISO 10646 standard published in March 2011.
