It really is just papering over the need to have the affected functions
conditional on their users. Not that is of any interrest for you, but
i'm backing this out of my copy, FWIW.

You forgot to specify which command to check. The proper invocation
would have read:
$(call check_ld,$(LD),--gc-sections,)
i.e. you have to specify which LD-binary you want to check.
That said, gc-sections seems to be on per default for the ld target i'm
usually using (i386 on linux), so it's a mere cosmetic "issue".

cheerio,
