gcc2: Allow the user to build non-PI executables

This aligns legacy gcc with the changes to gcc4 committed in 4192115 and
the two subsequent commits. It also disables legacy ld's default
behaviour of recursively resolving shared-library dependencies at link
time, preventing missing-library warnings during the build and aligning
ld's behaviour with that of more recent versions.

gcc2:

* CPP_SPEC: Replace non-existent command-line options with valid
equivalents.
* CC1_SPEC: Remove non-existent "no-fpic" option; add "fno-pic" and
"fno-PIC" 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, exporting all
symbols to match the behaviour of "-shared"; when building a
dynamically linked executable, do not recursively add shared libraries
as dependencies but do allow unresolved symbols in them; specify
"-Bsymbolic" only when building a shared library.
* All: Wrap lines at 80 columns; use more compact notation where
available.

ld:

* Do not recursively resolve shared-library dependencies when building
an executable if the "--no-add-needed" and "--allow-shlib-undefined"
options are in effect. This effectively backports binutils commits
8fbb09e and 4706eab.

* updated binutils to 2.17, most problems should be solved now...
except one: the binaries produced by this version of binutils crashes the loader of
BeOS versions BONE, Dano (and probably Zeta, too). That's a pity, but I currently
do not know how to fix this (as the fix available for older versions of binutils
does not work anymore).

Moved the old binutils to their new home.
