[PATCH v3 0/3] MR4492: configure: Use --no-default-config option on clang when available.
Some distros arbitrary flags into clang config files without guarding it for applicable targets, which breaks cross compilation.
-- v3: winegcc: Support --no-default-config argument. configure: Use --no-default-config option on clang when available. configure: Fix action-if-no handling in WINE_TRY_PE_CFLAGS macro.
