The generator requires the assembler internally, see `dwarfgen::Generator::generate()`. `dwarfgen::Generator::init()` creates `MCAsmBackend` and fails if the asm backend is not available.

After D98400 <https://reviews.llvm.org/D98400>, there are only two places where `isConfigurationSupported()` is still called, but right after the check, `dwarfgen::Generator` is created.
