  Log:
  Backout previous change of PICFLAG, since
  behaviour of -fPIC and -fpic are different.
  Here is the comment form obrien:
  
  --
  "-fpic" is a [minor?] optimization for machines that can handle it:
  
    -fpic
      Generate position-independent code (PIC) suitable for use in a shared
      library, if supported for the target machine. Such code accesses all
      constant addresses through a global offset table (GOT). The dynamic
      loader resolves the GOT entries when the program starts (the dynamic
      loader is not part of GCC; it is part of the operating system). If
      the GOT size for the linked executable exceeds a machine-specific
      maximum size, you get an error message from the linker indicating
      that -fpic does not work; in that case, recompile with -fPIC instead.
      (These maximums are 16k on the m88k, 8k on the SPARC, and 32k on the
      m68k and RS/6000. The 386 has no such limit.)
  
    -fPIC
      If supported for the target machine, emit position-independent code,
      suitable for dynamic linking and avoiding any limit on the size of
      the global offset table. This option makes a difference on the m68k,
      m88k, and the SPARC.
