Fix Solaris cc wrappers (re: 4e67234a)

Browse source 
The versions from the Solaris patch require $CC_EXPLICIT to be set,
which is specific to the internal Solaris build environment.

src/cmd/INIT/cc.sol11.*:
- Cope without $CC_EXPLICIT set in environment; fall back to $CC
  and if that is not set either, detect whether to use cc or gcc.
- Set appropriate flags for cc (Solaris Studio) or gcc, including
  the necessary -D_XPG6 flag, without which ksh crashes on Solaris.

bin/package, src/cmd/INIT/package.sh:
- Update hack to add the -D_XPG6 flag so it applies to gcc only
  (note: the src/cmd/INIT/cc.* scripts are never used for gcc).
