cmake: add workarounds for NixOS-specific deficiencies [NixOS]
The NixOS debug builder hook adds '-Wa,--compress-debug-sections' to the
link flags (it actually adds it to the compiler flags, but the compiler
is used for linking, so...). This makes the compiler angry when -Werror
is passed, because it's unused at link-time (-Wa applies to the
assembler). Suppress this warning with -Wno-unused-command-line-argument
NB: we *could* use -Wno-error=unused-command-line-argument, but that
still results in warnings anyway, just not fatal ones. We'd like to
remove them all for the sake of the build output.
