gcc4: revert partially 419211519c.

Browse Source 
"* 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.
