configure: Don't assume Gnu linker on Solaris

Compl Yue noticed that the linker was dumping the link map on SmartOS. This is
because Smartos uses the Solaris linker, which uses the `-64` flag, not
`-m64` like Gnu ld, to indicate that it should link for 64-bits. Fix the
configure script to handle the Solaris linker correctly.
