Commit: RX: Fix problems building libgcc

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a couple of problems building
  libgcc for the RX target.  The first is that when 32-bit doubles are
  enabled we need to make sure that we never try to construct a 64-bit
  double type.  This is done in rx-lib.h, but it was only being enabled
  when constructing the float-type functions.  The patch enables the fix
  for when double-type functions are being constructed as well.

  The second fix is to prevent a extraneous renaming of the floatsisf
  and floatunsisf functions when building libgcc width 32-bit doubles
  enabled.

Cheers
  Nick

	* config/rx/rx-lib.h: Always restrict doubles to the SF type when
	64-bit doubles are not enabled.
	* config/rx/rx-abi.h: Fix extraneous renaming of the floatsisf
	and floatunsisf functions.
