Comment (by MarcusCalhoun-Lopez):

 I am afraid I cannot reproduce this error.

 The first error
 {{{
 :info:build Undefined symbols for architecture arm64:
 -:info:build   "mbgl::style::IconAnchor::key", referenced from:
 -:info:build       void
 mbgl::style::conversion::stringify<mbgl::style::IconAnchor,
 rapidjson::Writer<rapidjson::GenericStringBuffer<rapidjson::UTF8<char>,
 rapidjson::CrtAllocator>, rapidjson::UTF8<char>, rapidjson::UTF8<char>,
 rapidjson::CrtAl\
 locator, 0u>,
 mbgl::style::SymbolAnchorType>(rapidjson::Writer<rapidjson::GenericStringBuffer<rapidjson::UTF8<char>,
 rapidjson::CrtAllocator>, rapidjson::UTF8<char>, rapidjson::UTF8<char>,
 rapidjson::CrtAllocator, 0u>&, mbgl::style::DataDrivenP\
 ropertyValue<mbgl::style::SymbolAnchorType> const&) in
 libqmapboxgl.a(symbol_layer.o)
 }}}
 must have something to do with improper generation of symbols
 {{{
 namespace mbgl {
 namespace style {
 struct IconAnchor : DataDrivenLayoutProperty<SymbolAnchorType> {
     static constexpr const char * key = "icon-anchor";
     static SymbolAnchorType defaultValue() { return
 SymbolAnchorType::Center; }
 };
 }
 }
 }}}

 My best guess is there is some other header file that is causing
 problems.\\
 Is it possible to temporary deactivate other ports and try the build
 again?
