But this has probably existed a long time.

Target: sparc-rtems4.11

I am testing gfortran on rtems and it appears that about 1/2 of the failures on
sparc are related to this.  

Some branches have  ",pn" and ",pl" attached and it is not supported.

  0x020012a4 <+36>:    ble,pn   %icc, 0x20013ec <foo_+364>
...
  0x020012f8 <+120>:    be,pn   %icc, 0x20013fc <foo_+380>

I checked sparc.c and there are some cases where the ",pX" are only generated
for sparc64 and others where they are not.

I don't expect this is hard to fix for a sparc maintainer. :)
