    testsuite: Use solaris_ld effective target
    
    Like the gas/solaris_as case, a testcase actually checks if Solaris ld
    is in use.  This patch uses the et-static framework to introduce a
    solaris_ld effective target for this.
    
    Other uses of the existing gld effective target are about GNU ld
    features and remain untouched.
    
    Bootstrapped without regressions on i386-pc-solaris2.11,
    sparc-sun-solaris2.11 (as/ld and gas/gld), and x86_64-pc-linux-gnu.

            gcc/testsuite:
            * lib/et-static.def (solaris_ld): New effective target.
    
            * g++.dg/eh/unwind-direct.C: Check solaris_ld instead of !gld.
    
            gcc:
            * doc/sourcebuild.texi (Effective-Target Keywords, Other
            attributes): Document solaris_ld.
