[Bug target/25376] New: section attribute doesn't work on darwin

[jconner at apple dot com]

Trying to assign a function to a user-named section fails on darwin in the 4.0,
4.1, and mainline.  For example, compiling this code:

  void specialfn (void) __attribute__((section ("__TEXT,__init")));
  void specialfn (void) {}

Places the function 'specialfn' into the default .text section instead of the
user-specified __init section.  From the assembly code:

          .text
          .align 2
          .globl _specialfn
  _specialfn:

Should be:

          .section __TEXT,__init
          .align 2
          .globl _specialfn
  _specialfn:

Perhaps - however, it's not been fixed on the 4.0 or 4.1 branches...

But this is not a regression so closing as fixed.
