Subject: [PATCH] Remove the GN settings done for clang that conflict with OE

clang cross compiler that is build with meta-clang has lot of these
settings built-in and specifying them here confuses the compiler

--target option and -no-canonical-prefixes options result in clang

finding the headers in target sysroot

Upstream-Status: Inappropriate [OE-Specific]
