Change gcc configuration to allow non-PI executables to be created

Subject: [PATCH 1/4] 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").
