When building with cc1 (Libreelec 8.2.5) I get following errors ( - for many files - ); reverting this commit e26ce3390a5ca88f3fcee8a7fa0e4bb1b078e538 solve it totally, what can be wrong?

I observed that when this checking goes "fail" (or commit is reverted in all cases) there are not errors and build finish.

  checking for cc strlcat ...                       ok
  checking for cc strlcpy ...                       ok
