Fix release and standards build flags (re: 3567220, aa4669a)

bin/package, src/cmd/INIT/package.sh: - CCFLAGS overwrites the autodetected optimisation flags (e.g. -Os) if set. Unfortunately, that also happened when we added something to CCFLAGS for a release build or to add an extra flag needed by Solaris. The fix is to use a new flags variable (KSH_RELFLAGS) instead. This needs to be done in a different place as it needs to be added to the mamake command as an assignment argument. - Remove the Solaris CCFLAGS hack; see features/common below. src/*/*/Mamfile: - Add ${KSH_RELFLAGS} to all the compiler commands. src/lib/libast/features/common: - Enable POSIX standard on Solaris (i.e.: if __sun is defined) by defining _XPG6 directly in the feature test that generates ast_std.h, which is indirectly included by everything. This removes the need to pass -D_XPG6 via CCFLAGS. (Doing so automatically with gcc was not otherwise possible.) src/cmd/INIT/cc.sol11.*: - No longer pass -D_XPG6, as per above.
