    Check for shared lib support before running ld tests with -shared
    
    Another fix now that we run these tests non-native.
    
    	* testsuite/ld-elf/audit.exp: Check for shared lib support.
    	* testsuite/ld-elf/compress.exp: Likewise.
    	* testsuite/ld-elf/dwarf.exp: Likewise.
    	* testsuite/ld-elf/shared.exp: Likewise.
    	* testsuite/ld-elf/wrap.exp: Likewise.
    	* testsuite/ld-ifunc/ifunc.exp: Likewise.
    	* testsuite/ld-plugin/lto.exp: Check $CXX exists.
