Added initial gcc deps for solaris 10

Allow solaris to use mapfiles

This change allows the optional use of a Solaris 10 linker mapfile.
It also updates the whitelist for Solaris 10 library healthcheck to
enable libraries that are 10+.

This also has 1 breaking change. solaris_compiler has been removed.
