Comment(by parcs):

 Replying to [comment:4 igloo]:
 > The linker flags are detected when a bindist is installed, not when it
 is built, so they should match the machine that GHC is run on.

 > Should we check what flags the linker supports every time ghc is run?

 Yeah, that sounds like a reasonable solution. The system linker may change
 after GHC is installed, and doing so shouldn't result in a non-functioning
 GHC installation.
