  Hi,

  This patch should fix the build breakage on aarch64-pe caused by the SFrame
  patch series.

  The issue was that the definitions related to SFrame APIs were not guarded by
  OBJ_ELF, they were errneously guarded by a more relaxed condition of OBJ_ELF
  || OBJ_COFF, hence causing build failures.

Testing notes:
  - Tested build and make -k check for selected folders for --target=aarch64-pe.

Thanks
Indu

---------------------

SFrame is supported for ELF only.  Keep the definitions and declarations
guarded with OBJ_ELF consistently.

ChangeLog:

	* gas/config/tc-aarch64.h:  Guard SFrame related definitions
	  with OBJ_ELF.

OK, but seeing as you are moving things around, let's move the above
three defines before the #else to get rid of another #if.
