[Buildroot] [PATCH 1/2] toolchain: introduce BR2_TOOLCHAIN_HAS_BINUTILS_BUG_30730

[Buildroot] [PATCH 1/2] toolchain: introduce BR2_TOOLCHAIN_HAS_BINUTILS_BUG_30730

[Giulio Benetti]

libheif package fails to build for the M68K architecture due to a binutils
bug that leads to:
Internal error in emit_expr_encoded at dw2gencfi.c:215

Let's add binutils bug to avoid to deal with architectures in packages
when a binutils bug arises. Let's instead deal directly with binutils
bug number.

It's been reported upstream:
https://sourceware.org/bugzilla/show_bug.cgi?id=30730

[Buildroot] [PATCH 2/2] package/libheif: let's use BR2_TOOLCHAIN_HAS_BINUTILS_BUG_30730

[Giulio Benetti]

Let's use binutils bug define instead of architecture checking in packages.

You forgot to update the Config.in comment dependency in
libheif/Config.in. Fixed that and applied to master. Thanks!
