[patch, testsuite, libgomp.fortran] darwin no longer requires static linkage to access TLS.

[IainS]

Hi All,

As discussed on IRC last night, Darwin targets no longer need -static- 
libgcc to provide TLS.  Consequently, the two tests that force this  
(libgomp.fortran/crayptr2.f90 and libgomp.fortran/pr32550.f90) can be  
tidied.

in each case:
-! { dg-options "-static-libgcc" { target *-*-darwin* } }
+! { dg-require-effective-target tls_runtime }

this is (IMO) the correct situation in any event - it seems misleading  
to force non-standard options to make a target pass a few tests.
checked on darwin9 ppc/i686 and darwin10 (thanks to Dominique).

cheers,
Iain

	*libgomp/testsuite/libgomp.fortran/crayptr2.f90 remove forced static  
linkage for darwin, protect the test with require-effective-target  
tls_runtime
	*libgomp/testsuite/libgomp.fortran/pr32550.f90 remove forced static  
linkage for darwin, protect the test with require-effective-target
