[Buildroot] [git commit branch/2020.02.x] package/gcc: fix check-package

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=219da1fbd1ad2bc58f587bf67e93ed7b1883f44d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Commit dcaf6e75a (package/gcc: pass -Wno-error to debug builds)
introduced non-ASCII characters in a comment, copy-pasted from a
terminal output.

check-package does not like non-ASCII characters, and whines about
them.

Replace the fancy quotes by standard ASCII ones.
