[committed] MIPS/LD/testsuite: Limit reloc 6 tests to DSO targets

[Maciej W. Rozycki]

Complement commit 500c05ddbe98 ("MIPS/ld/testsuite: Limit export class 
call reloc tests to DSO targets") and also check for target's shared 
library support in determining whether to run reloc 6 tests, which 
require it.  No changes in results as all targets currently enabled for 
NewABI testing support shared libraries.

	shared library targets.
