 Hadrian: support dynamically linking ghc

 * (#15837 point 5) Use the -rpath gcc option and using the $ORIGIN
 variable which the dynamic linker sets to the location of the ghc
 binary.
 * (#15837 point 4) "-fPIC -dynamic" options are used when building ghc
 when either ghc or the rts have a dynamic way.
 * (#15837 point 7) "-shared -dynload deploy" options are only used when
 linking a library (no longer when linking a program).
