configure: Default missing options to False when preparing ghc-toolchain Targets

This commit fixes building ghc with 9.2 as the boostrap compiler.

The ghc-toolchain patch assumed all _STAGE0 options were available, and
forgot to account for this missing information in 9.2.

Ghc 9.2 does not have in settings whether ar supports -l, hence can't
report it with --info (unliked 9.4 upwards).

The fix is to default the missing information (we default "ar supports
-l" and other missing options to False)
