ld: testsuite: Enable ld-shared tests on Solaris/x86

The ld-shared tests are run on Solaris/SPARC only for no apparent
reason.

This patch enables them on Solaris in general.  It leaves two XPASSes on
32-bit Solaris (both SPARC and x86), which I'll address in a followup.

Tested on {amd64,i386}-pc-solaris2.11 and sparc{v9,}-sun-solaris2.11.
