Draft: community/mingw-w64-gcc: use -fpermissive

Use -fpermissive for now to allow the source to compile due to multple instances of template errors.

Draft status:

• Could not downgrade errors using -Wno-error=template-id-cdtor -fpermissive flags.
• Build issue only for c++. When only --enable-languages=c,lto are enabled, the build runs successfully.
